Consider a frame that is made up of two thin massless rods A B and A C as shown in the figure. A vertical force P → of magnitude 100 N is applied at point A of the frame. Suppose the force is P → resolved parallel to the arms A B and A C of the frame. The magnitude of the resolved component along the arm A C is x N . The value of x , to the nearest integer, is ________. [Given : sin 35 ° = 0 . 573 ,
Correct answer
0
Step-by-step solution
Component along A C = 100 cos 35 °   N = 100 × 0 . 819   N = 81 . 9   N ≈ 82   N
