Two forces p and q are applied as shown to an aircraft connection. knowing that the connection is in equilibrium and that p = 500 lb and q = 650 lb, determine the magnitudes of the forces exerted on the rods a and b.

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
