Block A has a weight of WA = 200 N and block B has a weight of WB = 300 N. The coefficient of friction is us = 0.20 between all surfaces of contact. The blocks are connected by an ideal us cable that goes around a frictionless pulley. Given 0 = 25°, determine the force P for which motion of block B is impending down the incline.

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
