Question

1- What is torque? 2- What are the conditions for the equilibrium? 3- A uniform rod of length L-10 m, weight 490 N is used to support an object with weight Wi-343 N at a distance of x,-4 m and a second load of weight W2-196 N at a distance of x2-9 m. The rod is supported by a cable which is attached at x- 6 m and acting at an angle of 30 degrees with respect to the rod (a) What is the required tension in the cable? (b) Find the net horizontal force (magnitude and direction) that the pivot at the wall exerts in this loaded condition (c) Find the net vertical force (magnitude and direction) that the pivot at the wall exerts in this loaded condition. W, = m,8
