We begin by considering the forces exerted on a ring that is connected to a spring and that is free to slide along a rod. (See the top view diagram at right.)
Assume that the ring is massless and that the rod is frictionless.
- What is the n, force on the ring? (Hint: Consider what happens to the net force on an object as its mass approaches zero.) Explain.
Does the net force on a massless ring depend on the acceleration of the ring? Explain
What is the magnitude of the gravitational force exerted on the ring? (Recall that the ring is massless.)
Check that your free-body diagram is consistent with your answers to pans i and ii.
Would your answer above differ if you considered an instant when the free end was not at its farthest point from its equilibrium position? Explain.

- In the space to the right of the figure sketch a force diagram for the cart on the table. Suppose that the hanging mass is 120g. Calculate the net force on the system. If the mass of the cart was increased but the hanging mass remained the same, how would the acceleration be affected? Explain how you know in terms of net force and system mass. If masses on the cart were moved from the cart to the hanger, how would the acceleration be affected? Explain how you know in terms of net force and system mass. For a system mass of 600 g and a hanging weight of .5 N, determine the acceleration of the system.arrow_forwardThe previous step focused on friction for horizontal surfaces. As we discussed above, angled surfaces like the wedge below have different considerations. FN = mg cos(0) F₁ = mg F₁ = ? F₁ = ? Fy=mg cos(0) Specifically, we have the following considerations. 1. The normal force is not equal to mg. 2. There is a force acting along the angle of the wedge due to gravity. What is the coefficient of static friction ? Fx = mg sin(0) Let's consider the implications of this type of problem with the following examples. For all of the examples, the box has a mass of 25 kg. Imagine the box is on a surface that allows you to adjust the incline angle, 0. You find the maximum angle where the box remains stationary. That is, at any higher angle, and the box begins to slide. The static friction force at this maximum angle is 150 N. What is the angle 0 (in degrees)? Now you raise the incline to an angle of 60° greater than the angle of maximum static friction found above. At this angle, the box slides…arrow_forwardThe center of the Ferris Wheel is 36 feet above the ground. The wheel has a 32 foot radius and is turning at 30 degrees per second. a.)
