To measure the static friction coefficient between a 1.9 kg block and a vertical wall, the setup shown in the drawing is used.
A spring (spring constant = 418 N/m) is attached to the block. Someone pushes on the end of the spring in a direction perpendicular to the wall until the block does not slip downward. If the spring in such a setup is compressed by 0.070 m, what is the coefficient of static friction?© BrainMass Inc. brainmass.com September 25, 2018, 5:25 pm ad1c9bdddf - https://brainmass.com/physics/gravity/force-by-spring-135297
First draw all the forces on the block. There are four forces. The gravity mg, the friction f, the normal ...
It finds the coefficient of static friction between a block and a vertical wall. The solution is detailed and was rated '5/5' by the student who posted the questions originally.
