The bent uniform rod acd has a mass of 5 kg/m and is supported at a by a pin and at b by a cord. if the vertical shaft rotates with a constant angular velocity omega = 20 rad/s, determine the x, y, z components of force and moment developed at a and the tension in the cord.

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
