A tractor becomes stuck in the mud, and the operator plans to use a truck positioned at point A to pull it free. a. If a 400 lb force in the direction of the tractor’s chassis (i.e., in the direction from O to B) is sufficient to free it, determine the force the truck must produce in the cable. Also, determine the portion of the cable force that is perpendicular to the tractor’s direction, since in the tractor’s precarious condition this force will tend to tip it. b. If the trees were not present, determine the ideal location on the road where the truck should be positioned, with a short explanation of why.

Question

A tractor becomes stuck in the mud, and the operator plans to use a truck positioned at point A to pull it free.

a. If a 400 lb force in the direction of the tractor’s chassis (i.e., in the direction from O to B) is sufficient to free it, determine the force the truck must produce in the cable. Also, determine the portion of the cable force that is perpendicular to the tractor’s direction, since in the tractor’s precarious condition this force will tend to tip it.

b. If the trees were not present, determine the ideal location on the road where the truck should be positioned, with a short explanation of why.
