) A hydraulically operated multidisk plate clutch has an effective disk outer diameter of 160 mm and an inner diameter of d mm. There are six sliding planes. The coefficient of friction (f) is 0.20 and the maximum pressure (Pa) is 900 kPa. (a) Using the uniform wear model, estimate the axial force.
(b) Calculate the inner diameter of the plates for maximum torque and determine the maximum Torque
(hint: differentiate torque T with respect to inner diameter of d).

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
