My Home ent ERSION BACK NEXT Chapter 10, Problem 12 In e active o u o 12 discusses a method used to solve this problem. To measure the static friction coefficient between a .73 kg block and a vertical wall the s up shown in the drawing is used. A spring (spring constant 471 N/m) is attached to the block. Someone pushes on the end of the spring in a direction perpendicular to the wall until the black does not slip downward. If the spring in such a setup is compressed by 0.0518 m, what is the coefficient of static friction?

For equilibrium Fx = 0 and Fy =
sigma Fy = 0
uN = mg
sigma Fx = 0
kx = N
So, ukx = mg
u = mg/kx
= (3.73*9.81)/(471*0.0518)
= 1.499 Answer
