Solid Mechanics
Example - Problem 1 (1.7)
• Each of the four vertical links has an 8×36 mm uniform rectangular
cross section and each of the four pins has a 16 mm diameter.
a. Determine the maximum value of the average normal stress in the links
connecting points B and D

Solid Mechanics
Example - Problem 11 (2.13)
• Rod BD is made of steel ( = 200 GPa) and is used to brace the
axially compressed member of ABC. The maximum force that can
be developed in member BD is 0.02p. If the stress must not exceed
126 MPa and the maximum change in length of BD must not
exceed 0.001 times the length of ABC, determine the smallest
diameter rod that can be used for member BD.
