Majid Yaghoubi,Hamed Tavakoliow physiologic motion of the upper extremity with respect to the torso have been widely investigated. The acromioclavicular ligamentous complex (ACLC) including the deltotrapezial fascia and the individual coracoclavicular (CC) ligaments have been identified as important stabilizers against horizont

Hertzian Contact Stress, are developed within the contact areas. Theoretically, the contact is either a point (when at least one of theelements is a sphere) or a line (when at least one of the elements is a cylinder). High contact stresses may lead to failures such as cracks, pits and flaking in the surface material.In thi

Press-Connect Joints,ces. Since this kind of joining does not require any connecting parts such as keys and consequently any keyways or grooves in which the stress concentration occours, it has a high design strength (operational strength). In this chapter, we present graphs that simplify the press-joint design.

Rectangular Keys,tween them. Rectangular keys, alsocalled flat keys, are usually used for large shafts and are also recommended for small shafts where the shorter key height can be tolerated. Designing the key includes determining its dimensions (height, width and length) according to the transmitted torque and the
