A 7.3-kg ladder, 1.92 m long, rests on two sawhorses. SawhorseA, on the left, is located 0.30 m from the end, and sawhorse B, onthe right, is located 0.45 m from the other end. Chose the axis ofrotation to be the center of mass of the ladder.
a. What are the torques acting on the ladder?
b. Write the equation for the rotational equilibrium.
c. Solve the equation forFA in terms of Fg.
d. How would the forces exerted by the twosawhorses change if A were moved very close to, but notdirectly under, the center of mass?
