Calculate the pitch of a single-start square-thread of jack

Reference no: EM13715771

Solve the following questions:

Question I: Calculate the pitch of a single-start square-thread of a jack which will just allow the load to fall uniformly under its own weight.

Question II: The mean diameter of the thread is 8 cm and coefficient of friction of 0.08. If the pitch is 15 mm, what is the torque required to lower a load of 3 kN?

Express your knowledge to solve the above questions, thanks.
