Questions and Answers
Match the following terms with their respective calculation or reference:
Safe tensile load for a bolt of M36 = Permissible tensile stress * Cross-sectional area Shear stress at inner surface of a hollow shaft = Shear stress at outer surface * (External diameter / Internal diameter) Advantages of Hollow shaft over solid shaft = Refer Q.No. 1 , Pg.No. 2.29. Factors to be considered for design of machine element = Refer Art. 1.2 , Pg. No. 1.3.
Match the machine element parameter with its definition:
Pitch of screw thread = The distance between corresponding points on adjacent threads Torsional stiffness of a shaft = The ability of a shaft to resist deformation under twisting Permissible tensile stress = The maximum stress a material can withstand before failure under tension Shear stress = The force per unit area parallel to the face resisting the force
Match the machine design concept with its description:
Machine design = The process of creating new machines or improving existing ones Function of shaft = Transmit power from one end to another in various forms of machinery Design of machine elements = The process of creating individual components of a machine
