Final answer:
The tension in the cable is equal to the weight of the load, which is 700 lb. The force at the axle cannot be determined without additional information.
Step-by-step explanation:
In this problem, a 700-lb load is applied along the centroidal axis of a member. The centroidal axis is an imaginary line that passes through the centroid of the member, which is the point where the member's mass is evenly distributed.
To calculate the tension in the cable and the force at the axle, we need to consider the equilibrium of forces acting on the member. Since the load is applied along the centroidal axis, it does not create any moment about the axle. Therefore, the tension in the cable is equal to the weight of the load, which is 700 lb.
However, without more information about the member and the axle, it is not possible to determine the force at the axle. Additional information such as the geometry of the member and the position of the axle would be needed to calculate the force at the axle.
