Answer is:
bearing stresses
Explanation:
A localized compressive stress at the surface of contact between two members that are relatively at rest is known as bearing stress or crushing stress. The bearing stress is taken into account in riveted joints, cotter joints, knuckle joints etc. A key is subjected to side pressure as well at shearing forces. These pressures are called bearing stresses.
Answer is:
increase key width
Answer is:
ability to undergo large permanent deformations in tension
Explanation:
Ductility:
Ductility is the property by which a metal can be drawn into thin wires. It is determined by percentage elongation and percentage reduction in area of a metal. Also Ductility of a material can be defined as ability to undergo large permanent deformations in tension.
