Question 1.
What does it mean for a beam to be in equilibrium?
Show hintHide hint
Think about the balance of forces.
Question 2.
List the three equations of equilibrium.
Show hintHide hint
These involve forces in the x and y directions and moments.
3Question 3.
What do you use to visualize forces acting on a beam?
- A graph
- A spreadsheet
- A Free Body Diagram
Show hintHide hint
Think of a visual tool that's commonly used in physics.
4Question 4.
True or False: The summation of moments in equilibrium is always zero.
- True
- False
Show hintHide hint
Remember what we said about moments!
Question 5.
For a beam of length 8m with a load of 20kN located at 4m, calculate the reactions at both supports.
Show hintHide hint
Use symmetry when the load is in the center.
Question 6.
A beam is supported on both ends with a 15kN load positioned 3m from the left support. Calculate the reactions at both supports.
Show hintHide hint
Consider distance when calculating moments.
