Exam-style question
Try this first
A uniform beam of length 4 m and weight 200 N is supported at its midpoint. If a 100 N weight is hung 1 m from one end, calculate the reaction force at the support point.
Model answer
What a good answer should say
- The reaction force at the support point is 250 N.
Explanation
Why this works
This question assesses the understanding of equilibrium and the application of moments. The total downward force must equal the total upward force for the beam to be in equilibrium.
The calculation involves balancing the moments about the support point.
