Longitudinal static stability of boeing 737 max 8
The document discusses the longitudinal static stability of the Boeing 737 MAX 8 aircraft. It provides specifications of the Boeing 737 MAX-8 and its LEAP 1B engines. The replacement of the original engines with larger LEAP engines affected the static stability of the aircraft by changing the static margin and causing the elevator to trim differently with various center of gravity positions. This contributed to the Lion Air and Ethiopian Airlines crashes that killed 346 people. Analytical calculations are shown relating center of gravity, coefficient of lift, static margin, elevator trim, and maximum climb angle. The reasons for the crashes are justified using this data.

3 axles
The document discusses different types of axles used in vehicles. It describes front axles which support the front of the vehicle and facilitate steering. Front axles can be dead axles, which do not rotate, or live axles which transmit power to the front wheels. Rear axles support the weight of the vehicle and transmit driving thrust. The document outlines full-floating, semi-floating, and three-quarter floating rear axles and how they differ in how they carry weight and transmit torque. It also discusses stub axles which connect to the front axle and allow the front wheels to turn for steering.
6 rear axle drives
The document describes two types of rear axle drives: the Hotchkiss drive and the torque tube drive. The Hotchkiss drive uses two longitudinally mounted leaf springs connected to the frame with a fixed pivot in front and swinging shackles in back. A universal joint is used at each end of the propeller shaft to accommodate changes in shaft length from spring deflection. The torque tube drive uses a tubular torque tube that encloses the propeller shaft and is bolted to the axle casing. A universal joint and ball socket joint are used to allow the propeller shaft to angle within the torque tube as the suspension moves.
Chapter 01

For RWD, it describes how universal joints and slip joints allow the driveshaft length and angle to change as the rear axle moves up and down. It also discusses phasing of joints to reduce speed fluctuations. For FWD, it outlines the major components including fixed and plunge constant velocity (CV) joints, and how they allow the driveshaft to bend during turning and change length when wheels move vertically.
How differential works
The document summarizes the key components and functioning of a differential assembly. It describes the main parts like the pinion gear, ring gear, differential case, and rear axles. It explains how the differential transfers power from the driveshaft to the wheels while allowing them to rotate at different speeds during turns. The document also briefly discusses hypoid gears, limited-slip differentials, transaxles, universal joints, and common differential problems.
AUTOMOBILE UNDER CHASSIS
The document discusses various vehicle chassis and suspension system types. It describes ladder, backbone, and monocoque chassis designs. It also outlines independent and dependent suspension systems such as MacPherson strut, double wishbone, and beam axle designs. Finally, it discusses hydraulic, pneumatic, mechanical, electronic, and vacuum brake systems as well as steering system types like recirculating ball gearbox, power steering hydraulic, and power steering electro-hydraulic.
12 rear axle casing
The document discusses three types of rear axle casings: 1) Split type which has two halves bolted together and requires removing the entire rear axle for repairs; 2) Banjo or separate carrier type which has a one-piece casing that carries the differential unit and allows removing half shafts for repairs; and 3) Salisbury or integral carrier type which is like the banjo type but has permanent housing tubes welded to the differential housing, making it the most widely used type today.
11 final drive
The rear axle final drive (1) transmits power at a 90 degree angle from the transmission and (2) reduces the engine speed to provide the transmission's top gear ratio. (3) Cars typically use a final drive ratio of around 4:1. Bevel, hypoid, and worm gears are commonly used in final drives to achieve the necessary functions.
Differentail
- The drive pinion drives the ring gear which is attached to the differential case. When going straight ahead, power is transferred equally to both wheels. When turning a corner, the wheels must travel at different speeds to prevent tire scrubbing, so the differential pinion gears "walk" around the slower side gear to cause the other side gear to turn faster.
- Limited-slip differentials limit the amount of differential action allowed compared to open differentials. They provide more driving force to the wheel with traction when one wheel begins to slip while still allowing wheels to turn at different speeds when cornering.
- In operation, driving torque is transmitted equally to each axle until traction is lost by one wheel. Then
Differential and Rear Axle Drives, by Jeevan B M
A differential is a device capable of transmitting torque and rotation through three shafts, almost always used in one of two ways.
Rear axle drives are the drives which employed for the rear axle the spring take the weight of the body.
Chap70
The document provides information about various components in hydraulic brake systems, including:
1) A residual check valve keeps slight pressure in the system to prevent air leaks, while proportioning valves limit rear brake pressure to improve balance during hard stops.
2) A pressure-differential switch lights the brake warning light if pressure is lost in one circuit, while a brake fluid sensor does the same for low fluid level.
3) Common valves like metering valves and electronic proportioning systems work to properly time and balance brake pressure between the front and rear.

Chap80
The document provides information about vacuum brake boosters, including:
- Vacuum brake boosters use engine intake manifold vacuum and pressure differential to multiply brake pedal force applied by the driver.
- They contain one or two rubber diaphragms connected to the brake pedal and master cylinder. Opening an atmospheric valve allows air pressure to assist braking.
- Vacuum boosters are tested by depleting vacuum stored in the booster and ensuring the brake pedal drops when the engine is restarted, indicating restored vacuum power assist.

Detection of Gear Fault Using Vibration Analysis
This document presents a study on detecting gear faults in a gearbox using vibration analysis and motor current signature analysis. The experimental setup consists of a gearbox coupled to an induction motor. Vibration data is collected from the gearbox using an accelerometer under different load conditions and gear operations. Motor current is also measured using current probes. The results show that vibration parameters and motor current values change with the introduction of gear faults like removed teeth. The analysis of motor current signatures provides a non-intrusive way to monitor the condition of an inaccessible gearbox by detecting faults that cause modulations in the current waveform.
