A slider-crank mechanism is required to do the following crank angle-slider position coordination. Crank Angle (Q) Slider Position(S) Position-1 0° 12 cm Position-2 90° 10 cm Also at position 2, the speed of the slider will be 5 cm/sec leftwards as the crank is rotating CCW by 1 rad/sec. Then verify your design by drawing your mechanism at crank angles 0° and 90° and measure slider position and see if they are 12 cm 10 cm respectively. If so, proceed with a velocity analysis at second position, assuming that crank has a speed of 1 rad/sec CCW and find the slider speed , check whether it is 5 cm/sec leftwards or not.
Aim: To conduct a full kinematic analysis and calculate dynamic reaction forces in a linkage mechanism, calculate instantaneous torque, required to drive the mechanism and to present the results of the case study in a clear reporting format. Introduction: Figure 1 shows a pumpjack operating at an oil well. Its representation as a linkage is also shown in Figure 1. The pumpjack is driven by a motor attached to crank OA. A constant torque T is applied to the crank and the crank rotates at a constant angular velocity ???. A force P is applied vertically downwards at the end of the walking beam BD, which has its centre of mass at point G. To design the mechanism, a careful kinematic analysis of the mechanism needs to be conducted. To avoid mechanical failure and to provide adequate support to the mechanism, the engineer needs to analyse the reaction forces in the joints. Masses of links OA and AB are assumed to be smaller in comparison with the mass of BD and are ignored in the analysis.…

Q3. Audi’s design of their R8 model is designed in order to have the engine in the rear of the car with the following schematic of their mechanical power transmission. The engine is connected to the gearbox, where gear change occurs and then a driveshaft is used to transfer an equal ratio of power balancing the rear and front wheel power output thus referring to it as an all-wheel drive. The vehicle has been modified by a customer thus resulted to no power transfer to the front wheels although the rear wheels still have the same power output. Using your knowledge, DEFINE and JUSTIFY the possible reasons of why the front drive isn’t functioning. What are the solutions to this fault?
A slider-crank mechanism is required whose slider is at position 12 cm when its crank is at 90°. Further, the velocity of the slider will be 5 cm/sec leftwards when input crank speed is 1 Rad/sec CCW. At the given position and acceleration of the slider will be 2 cm/sec² leftwards when input crank speed is constant. Design the mechanism and do a position, velocity and acceleration analysis to verify your design.

Task 1): The quarter-car model of a vehicle suspension and its free body diagram are shown in Figure 1. In this simplified model, the masses of the wheel, tire, and axle are neglected, and the mass m represents one-fourth of the vehicle mass. The spring constant k models the elasticity of both the tire and the suspension spring. The damping constant c models the shock absorber. The equilibrium position of m when y=0 is x=0. The road surface displacement y(t) can be derived from the road surface profile and the car's speed. a) Draw free body diagram (FBD) and derive the equation of motion of m with y(t) as the input, and obtain the transfer function.
