Answer 1

Answer #1

To calculate the torques, we need to determine the lever arms for each of the forces. These lever arms are shown in the following drawings:

Axis Axis _ 32.0° 2.50 m 32.0° 2.50 m - l = (2.50 m) cos 32.0° lw= (2.50 m) sin 32.0°

(a)We find that the magnitude of the torque due to weight W is

Magnitude of Torque = W l_w = (13600N)(2.50m) sin 32.0^o = 18017.25 N.m

(b) The magnitude of the torque due to thurst T is

Magnitude of Torque = T lT = (61000N)(2.50m) cos 32.0^o = 129327.33 N.m
