Question

For frames and machines, the first thing that you should usually do is:

a) Solve for support reactions
b) Calculate the centroid
c) Apply equilibrium equations
d) Determine internal forces

Answer 1

When analyzing frames and machines, the first step is to solve for support reactions by using static equilibrium equations to find the forces and moments at the supports.

Step-by-step explanation:

The first step you should usually take when analyzing frames and machines is to solve for support reactions. This involves applying static equilibrium equations to the entire structure or machine to determine the forces and moments at the supports. Once these support reactions are known, you can then proceed to calculate internal forces in various members of the frame or machine components.
