This document discusses the analysis of structures including trusses, frames, and machines. It defines trusses as structures formed from two-force members connected at joints. Trusses can be analyzed using the method of joints or sections. Frames contain multi-force members and may cease to be rigid when detached from supports. Machines are designed to transmit and modify forces and transform input to output forces. Sample problems demonstrate applying equilibrium conditions to determine member forces and reactions.

Rc helicopter
This document provides an overview of remote control helicopters, including their different types, parts, control methods, and flight techniques. It discusses the main rotor system parts like blades, hub, and mast. It explains the swash plate and how the collective, cyclic, and anti-torque controls are used to manage lift, direction, and torque. Precise hovering requires continuously adjusting the cyclic, collective and pedal inputs. Setting with power is one of the most dangerous flight situations for a helicopter pilot.
Mast Bumping
The document discusses mast bumping in helicopters. Mast bumping occurs when the rotor head impacts the main rotor shaft, usually due to excessive flapping caused by flying outside the helicopter's safe operating envelope. It most commonly affects two-bladed rotor systems. Mast bumping can result from abrupt cyclic or collective control inputs combined with low or negative G-forces. Under these conditions, there is little thrust generated and the fuselage rolls uncontrollably due to the tail rotor thrust. To recover, positive load must be restored to the rotor by applying back cyclic and collective pitch.

- The angle of twist is proportional to the applied torque, material properties, and shaft length based on elastic torsion formulas.
- Stress concentrations can occur due to geometric discontinuities and influence the maximum shearing stress.
Types of stresses

Simple trusses follow the rule that the number of members m equals 2n-3, where n is the number of joints. The document describes two common methods for truss analysis: (1) the method of joints, which uses equilibrium equations at each joint to solve for member forces, and (2) the method of sections, which uses equilibrium of a portion of the truss cut out by a section. Sample problems demonstrate applying each method to determine member forces in specific trusses.

An introduction to the module is given, including forces, moments, and the important concepts of free-body diagrams and static equilibrium. These concepts will then be used to solve static framework (truss) problems using two methods: the method of joints and the method of sections.Truss
The document defines a truss as a rigid structure composed of two force members connected at joints. There are three types of trusses: perfect trusses which have just enough members to remain stable under loading, deficient trusses with too few members, and redundant trusses with excess members. The key assumptions in truss analysis are that members are pin jointed and carry only axial forces, and trusses are loaded at joints. Two common methods to analyze trusses are the method of joints, which determines member forces by analyzing joints individually, and the method of sections, which analyzes equilibrium across a cut through selected members. Several example problems demonstrate applying these analysis methods to various truss configurations.

Trusses The Method Of Sections
The document discusses different types of structures and methods for analyzing trusses. Trusses are structures made of straight members connected at joints. Two common methods for analyzing trusses are the method of joints and method of sections. The method of joints involves drawing force diagrams at each joint and applying equilibrium equations. The method of sections involves cutting a truss and analyzing one side of the cut section. Zero-force members, which carry no load, can be identified and removed to simplify analysis.

The Northrop F-20 Tigershark was a privately developed fighter aircraft intended to compete with the F-16 Fighting Falcon. It began flying in 1982 but failed to secure any orders due to the US relaxing restrictions on F-16 sales. While the F-20 had performance comparable to early F-16 models, its airframe was based on the older F-5 design with limited expansion capabilities. The last prototype is displayed at the California Science Center.
