1. For the instant shown when the crankpins of a two-cylinder engine pass through the horizontal y- z plane, connecting rod A is under a compression of 1.8 kN and rod B is under a compression of 0.8 kN. Determine the moment (torque) exerted by the two rods about the crank axis z. For design purposes it is also necessary to have the vector expression for the moments of the two forces about one of the main ball bearings at O.

2. The threading die is screwed onto the end of the fixed pipe, which is bent through an angle of 20°. Replace the two forces by an equivalent force at O and a couple M. Find M and calculate the magnitude m = 39, of the moment which tends to screw the pipe into the fixed block about its angled axis through O.
