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?

Explanation / Answer

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
