Find the tension in the string AB loaded with weight W at the middlw, when AB is horizontal:

Find the tension in the string AB loaded with weight W at the middlw, when AB is horizontal:

In the given figure the tension in the string OB is 30N. Find the weight 'W and the tension in the string OA.

As shown in figure the tension in the horizontal cord is 30 N . The weight W and tension in the string OA in Newton are

As shown in figure the tension in the horizontal cord is 30 N . The weight W and tension in the string OA in Newton are

A block is pulled a distance x along a rough horizontal table by a horizontal string. If the tension in the string is T, the weight of the block is W, the reaction is N and frictonal force is F. Write down expressions for the work done by each of these forces.
