QUESTION 1 In the crank-connecting rod mechanism shown in Figure 1, friction between the piston and the cylinder is neglected. Find the M12 torque required for the static balance = to be at the given crank position. (O2A = 75 mm, AB = 350 mm, P-0.9 kN)

Answer 1

I am answering the only second one. Sorry for inconvenience.
