... aids in the understanding of the next part 26 The free-body diagrams are shown below T is the magnitude of the tension force of the string, f is the magnitude of the force of friction on block A,... friction forces (there are four of them, one for each thumb and one for each set of opposing fingers) equals the magnitude of the (downward) pull of gravity Using Eq 6-1 , we have µ s FN = mg = (79... Problem 6-3 We merely quote (and apply) their main result (Eq 6-1 3) for the maximum angle for which static & friction applies (in the absence of additional forces such as the F of part (b) of this
