Question

64 The general procedure for the solution of motion-impending friction problems in this text involves drawing the free-body diagram and deciding which way motion is impending. This is followed by the application of Equation (6.2) and the equa- tions of force equilibrium for concurrent force systems, or the equations of force equilibrium and moment equilibrium for noncurrent force systems. ccil ull the e Darts, the iCieht thread. The lead angle is calculated from lead, and mean radius of the θ = tan-1-= tan-11 (6.10) 6.8 The equations of equilibrium and frictional considerations can be used to determine the force Prequired to move a screw within a threaded block.
