3 analysis
1. The document discusses two methods for analyzing trusses: the method of joints and the method of sections.
2. The method of joints involves satisfying equilibrium conditions at each joint to solve for member forces. The method of sections allows analyzing any member directly by considering equilibrium across a cut through the truss.
3. A sample problem demonstrates applying the method of sections to calculate three unknown member forces in a cantilever truss subjected to a 20-ton load. Free body diagrams and moment sums are used to determine member forces independently.
Trusses Joints
1) The document discusses trusses and methods for analyzing truss structures.
2) A truss is a structure composed of slender members joined at endpoints that can support loads. The method of joints is introduced to analyze trusses by applying equilibrium equations at each joint.
3) Zero-force members, which do not experience internal forces, are identified through applying the method of joints and considering the geometry and external loads on the truss. Identifying zero-force members simplifies the analysis.
Summary
This document discusses vectors, force systems, and moments of force. It provides examples of torques, moments, and the cross product as they relate to force vectors. It also uses a skateboard and a hinged rectangular platform suspended by a cable as examples to illustrate moments of force and bending stresses. The document aims to explain vectors with force systems and resultants, and how moments are calculated as both scalar and vector formulations. It concludes with a problem asking the reader to find the moment about each coordinate axis of the force exerted by a cable suspending a hinged platform.

3 summary
This document discusses concurrency control techniques for managing concurrent execution of transactions. It provides an example of how concurrency control is needed when multiple passengers try to purchase the last remaining airline ticket. The document then covers topics like transaction serialization, pessimistic and optimistic concurrency control, locking techniques, and two-phase locking. It concludes with sample multiple choice questions about problems with concurrent transactions, methods for serialization, locking data items, and definitions of deadlock and concurrency control.
2 con control
This document discusses concurrency control techniques for databases, including pessimistic and optimistic concurrency control. It describes locking techniques used for synchronization, including binary locks, certify locks, and two-phase locking to ensure serializability. It also discusses problems that can occur with locking such as deadlocks and starvation.
1 con exe
This document discusses concurrency control and methods to ensure serializability when transactions execute concurrently in a database. It begins by describing three problems that can occur with concurrent transaction execution: lost updates, unrepeatable reads, and dirty reads. It then explains two methods for achieving serializability: multi-version concurrency control and timestamp ordering. Timestamp ordering assigns timestamps to transactions and data items and uses the timestamps to determine when transactions can read and write data items to prevent conflicts. The document also briefly mentions using concurrency control protocols that employ locking to serialize transaction access.
1 basic concepts
This document discusses transaction processing in online transaction processing (OLTP) environments. It covers typical OLTP environments like airline, banking, and trading systems. It also covers topics like transactions being atomic units of execution that must have ACID (atomicity, consistency, isolation, durability) properties and can be in different states during processing. Transactions are sequences of database operations that must generate a consistent database when applied to a consistent one.
2 recovery
The document discusses database recovery from failures. It explains that a DBMS uses techniques like logging transactions, periodic backups, and mirroring databases to restore the system to a consistent state if a failure occurs. There are two types of recovery - from transaction failures, where the DBMS undoes uncommitted transactions, and from catastrophic failures like disk or system crashes, where the entire database must be restored from a backup and the log is used to replay committed transactions. Proper recovery is needed to ensure transactions are fully committed or have no effect, and that the database remains in a consistent state.
3 transaction
The document discusses the ACID properties that transactions should possess:
1. Atomicity - Transactions are atomic units that are fully completed or not completed at all.
2. Consistency - Transactions preserve consistency by ensuring the database only transitions between valid states.
3. Isolation - The execution of one transaction is isolated and not interfered with by other concurrent transactions.
4. Durability - Committed transaction changes persist in the database and survive failures through logging and recovery.
3 summary
The document discusses query processing and optimization techniques. It provides an example of querying a database to find the name of the last member to borrow a book with the title "Zeus". There are several ways to structure the query, but some methods are more optimized than others. Query processing involves translating SQL queries into relational algebra operations, generating execution plans, and executing the queries. Query optimization examines multiple query plans to identify the most efficient plan to retrieve the required data.
1 query processing
The document discusses the process of query processing, which includes translating SQL queries into relational algebra, generating an evaluation plan, and executing the query. It provides examples of translating a SQL query into relational algebra expressions and generating an annotated evaluation plan specifying the detailed strategy for evaluating the query.

2 optimization
The document discusses query optimization techniques used by database systems. It describes how a database catalog is used to estimate query execution costs. Alternative execution plans are enumerated using heuristic rules and the lowest cost plan is selected. Examples are provided of applying translation rules to optimize a query tree by pushing down select and project operations, avoiding Cartesian products, and reordering joins and selections. Cost estimation considers factors like I/O, memory usage, and computation to select a suboptimal but efficient execution plan.
2 collision
This document discusses collisions, center of mass, and impulse and momentum. It provides information on inelastic 2D collisions and notes that analyzing collisions using impulse and momentum is useful when solving for collisions between two bodies. It also defines center of mass as the point where all the mass of an object or system can be considered concentrated.

This document discusses database design concepts and normalization theory. It covers topics such as functional dependency, the first, second, and third normal forms, benefits of normalization like minimizing data redundancy, and concepts of denormalization. It includes a quiz to test understanding with questions about the goal of normalization, benefits of normalization, characteristics of third normal form, database anomalies, and the definition of denormalization.
2 normalization
This document discusses normalization, which is the process of organizing data in a database to minimize redundancy and dependency. It defines normalization through various normal forms, including first normal form (1NF), second normal form (2NF), and third normal form (3NF). These normal forms help reduce data anomalies like insertion, deletion, and update anomalies that can occur when data is redundant or dependent on other data. The benefits of normalization include using less storage space, allowing for quicker updates, and reducing data inconsistencies.
1 fn dependency
This document discusses functional dependencies in database relations. It defines functional dependency as a relationship where the value of one attribute (the dependent attribute) is determined by the value of another attribute or set of attributes (the determinant attributes). It provides examples of functional dependencies, such as child being functionally dependent on mother, but not vice versa. The document also includes an example employee database relation showing the primary key of empno and functional dependencies between attributes.
4 summary
