- What tyre wear pattern will result from excessive negative camber?(Automotive cert.4)If the travel ratio of a tractor was found to be 0.90. What is the % slip (wheel slippage)? *5 Answer the following: a) Briefly describe the difference between a bias ply and radial tyre. b) Draw a diagram showing the lateral force vs. slip angle for both a radial tyre and a bias ply tyre.
- The speed of the bus should reach to the top speed of 90-100 km/hr, was a technical requirement. While doing functional analysis, the system engineering team changed this requirement like this: Euro 3 engine is required with torque 1200 nm and maximum rpm 2100. The body weight should be reduced and aerodynamically designed. Special tire to withstand the speed." At which process step will this discussion happen and discuss the next step if any.Define what is the Gough Diagram in tire dynamics.b) If all axles must be operational for the vehicle to function and the reliabilities are measured over a 100-day mission, calculate the MTTF of the vehicle assuming a constant failure rate for each tire. • MTTF = 80 d • MTTF = 183 d • MTTF = 128 d • MTTF = 100d
- OBSERVATIONS 1. Differentiate between static and kinetic friction. 2. Differentiate between rolling and sliding friction. 3. For which combination of materials, the coefficient of static friction is lower? Why? 4. Always rolling friction is greater that sliding friction. True/False CONCLUSIONThe tire has a radius of 9 ft and a radius of gyration of 2 ft. r ft What must be the coefficient of friction to make sure that the tire is uniformly accelerated (acceleration not equal to zero) in the inclined plane for an angle of 25°?G. 5 ft 2 ft 7 ft The train has a weight of 23000 lb and a center of gravity at G. It is suspended from its front and rear by a total of six tires. The rear three tires, A, B, and C are shown in the diagram. All surfaces are smooth and it is assumed that the front and rear tires carry equal portions of the weight. For all answers, the sign corresponds to the given coordinate system.
