Assignment 6 1. A hook is screwed into a ceiling; one end of a string is tied to the hook and the other end has an 8-kg mass attached to it. Assuming that the force of gravity acting on a mass m has magnitude mg, where g=9.8 m/s2, what force does the hook exert on the string. 2. A force of magnitude of 8 N pushes on a horizontally stacked set of blocks on a frictionless surface (figure below) with a masses m1 = 2 kg, m2 = 3 kg, m3 = 4 kg. a. What is the acceleration of the stack? b. What are the forces on block 1 as well as the net force on this block? c. Repeat part b for block 2.

Unformatted text preview: d. Repeat part b for block 3. 3. Two blocks of masses M and m are connected by a light rope that passes over a frictionless pulley. Mass M sits on an inclined plane with an angle of inclination of θ = 30 degree. The coefficient of static friction between mass M and the inclined plane is 0.2, while m = 3 kg. Determine the largest and smallest possible values of M for which the system remains in equilibrium. Calculate the force of static friction on the block of mass M if M = 6 kg. F = 8 N M1 M2 M3 Solution 1. 2. 3....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
