An end milling operation is being carried out on a 500 mm long and 80 mm wide aluminum alloy block to make a slot of 50 mm in width and 3 mm in depth. the cutting operation is done at a feed rate of 0.6 m/min. the cutter diameter is 50 mm, with 10 cutting inserts, and the tangential speed of the cutter is 50 m/min. calculate the material removal rate, cutting time, feed, and estimate the power required for cutting.

If a particle moves along a path such that r : (3 sin t) m and ? : 2t rad, where t is in seconds. what is the particle's acceleration in m/s in 4 seconds? a)- 16.43 b)- 16.29 c)- 15.21 d)- 13.79

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
