Which one of the below statements is true? O a. Kutzbach formula (or criterion) is always reliable in predicting the actual degrees of freedom for any mechanism. Ob. Springs are considered as links for degree-of-freedom calculations. OC. For a grounded link rotating with constant angular speed, the magnitude of the velocity vector of a point increases as the point moves away from the pivot. O d. Satisfying the Grashof criterion means that none of the links in a mechanism makes full rotations.

Metrology of Screw Threads

Screw threads are a series of ridges having the profile of a helix. This helix profile runs continuously along the length of a uniform solid or a hollow bar of a circular cross-section at periodic intervals. These helix ridges are also formed over a conical bar. These continuous helical ridges are termed threads.

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 crank-slider mechanism is constructed so that the slider operates in a horizontal plane 3 inches below the horizontal plane in which O2 falls. O2B = 4.5 inches (crank; O2 is pivot) BC = 12 inches (coupler). Please analyze the mechanism and provide the following: -When the mechanism is in the extended position, what is the distance between the crank pivot point and the slider joint? -When the mechanism is in the collapsed position, what is the distance between the crank pivot point and the slider joint? -What is the stroke of the slider? -When the mechanism is in the extended position, what is the horizontal distance between the crank pivot point and the slider joint? -When the mechanism is in the collapsed position, what is the horizontal distance between the crank pivot point and the slider joint?
