1. A V-belt drive with an included angle of 34° is to have a capacity of 15 kW based on a coefficient of friction of 0.2 and a belt weight of 2.5 N/m. Determine the required maximum belt tension at full load. Assumptions: The driver is a normal torque motor and the driven machine involves heavy shocks. Design Decision: Speed is to be reduced from 2700 to 1800 rpm using a 200 mm diameter small sheave: shafts are 500 mm apart.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

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
