Chapter 3, Problem 13PQ
In Chapter 5, you will study a very important vector, force. Each case in Figure P3.13 shows an example of force vectors exerted on an object. These forces are all of the same magnitude F0. Assume that the forces lie in the plane of the paper. Rank the cases from greatest to smallest according to the magnitude of the total force. Note: The total force is the vector sum of the individual forces exerted on the object.

The upper pulley is attached to the ceiling by a chain, and the lower pulley is attached to the weight by another chain. The weight is lifted at constant speed. Assume that the rope, pulleys, and chains all have negligible weights. In terms of w, find the tension in the lower chain. In terms of w, find the tension in upper chain. In terms of w, find the magnitude of the force F if the weight is lifted at constant speed.arrow_forwardTwo crates connected by a rope lie on a horizontal surface (Figure 1).

The distance they need to drag the equipment is 10m. Knowing that the coefficient of kinetic friction between the equipment and the floor is 0.3. The figure below shows a top view, where the arrows represent the friction forces and the forces applied by the students. Given that θ=20° , that the forces A1(vector) and A2(vector) have the same magnitude and are symmetrical to the horizontal, and that the equipment was dragged at constant speed, calculate the work done by the friction force and the students in moving the equipment.arrow_forwardHi, I have to on a graph vectors that illustrate this problem. Suppose you have to move a heavy crate of weight 875 N by sliding it along a horizontal concrete floor. You push the crate to the right with a horizontal force of magnitude 300 N, but friction prevents the crate from sliding. I have tried to have the forces in the right direction. Normal force is vertically up, weight is down, friction force is in the opposite direction to force. But I'm still not getting the graph right. Not sure if the lengths of the forces have something to do with it.arrow_forward
