A 900-N boy sits on top of a ladder of negligible weight that rests on a frictionless
Question:
A 900-N boy sits on top of a ladder of negligible weight that rests on a frictionless floor as in Figure. There is a cross brace halfway up the ladder. The angle at the apex is q = 30o.
(a) What is the force exerted by the floor on each leg of the ladder?
(b) Find the tension in the cross brace.
a-900 N e = 30
Step by Step Answer:
a The force exerted by the frictionless floor must be vertical By symmetry each le...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
