2011-3-29  110 Machine Design The force P has to overcome the friction as well as cause lifting of the body in vertical direction. To find the relationship between force P, called effort, and weight of the body, W, we have to consider the equilibrium of the body on an inclined plane as shown in Figures 5.7(a) and (b). The free body diagram clearly shows forces along and

2011-8-2  The Ball Screw requires a minimal starting torque due to its rolling motion, and does not cause a slip, which is inevitable with a sliding motion. Therefore, it is capable of an accurate micro feeding. Fig.4 shows a travel distance of the Ball Screw in one-pulse, 0.1-μm feeding. (LM Guide is used for

A comparison of screw insertion torque and pullout strength

Purpose: Pullout strength of screws is a parameter used to evaluate plate screw fixation strength. However, screw fixation strength may be more closely related to its ability to generate sufficient insertion because stable nonlocked plate-screw fracture fixation requires sufficient compression between plate and bone such that no motion occurs between the plate and bone under physiological loads.
