Spec 1.33P
What you need to know
- Draw the forces on a supported beam
- Use vertical force balance
- Use moments to find how support forces change
Active recall
Quick check
Answer each question before opening the answer.
What equation gives vertical force balance?
RA + RB = W
Why take moments about a support?
Its reaction then has zero moment, simplifying the calculation
What happens to RB as the load moves toward B?
RB increases
