Answer: The two blocks used in a measuring device have
Chapter 8, Problem 8-61(choose chapter or problem)
The two blocks used in a measuring device have negligible weight. If the spring is compressed 5 in. when in the position shown, determine the smallest axial force P which the adjustment screw must exert on B in order to start the movement of B downward. The end of the screw is smooth and the coefficient of static friction at all other points of contact is \(\mu_{\mathrm{s}}\) = 0.3
