Problem 27P

Problem

(II) Two snowcats in Antarctica are towing a housing unit north, as shown in Fig. 4-50. The sum of the forces exerted on the unit by the horizontal cables is north, parallel to the line L, and FA =4500 N. Determine FB and the magnitude of

Solution 27P: Force is a vector quantity since it provides the magnitude as well as the direction in which it acts. We have to find the individual magnitude of force applied and their vector sum as per the given condition. Step 1 of 4 Concept: Newton’s second law: The net force F acting on an object of mass m produces an acceleration a in the object. Mathematically, F = ma. Free body diagram of a body gives the diagrammatical representation of all the forces acting on the body in terms of magnitude and diagram, under the given situation.
