PROBLEM E2.5. A vertical force P on the foot pedal of the bell crank mechanism is required to produce a tension T of 400 N in the vertical control rod. Determine:
1)The corresponding bearing reactions (resultant reactions) at A and B,
2) the directional cosines of bearing reactions at A and B,
3) the torque (couple/moment) produced by force P about the z-axis.
