Question: For a simply supported beam with a length L and a point load P at one end, what is the reaction at the other end?

Options:

Correct Answer: P

Solution:

The reaction at the other end of a simply supported beam with a point load P at one end is equal to P.

For a simply supported beam with a length L and a point load P at one end, what is the reaction at the other end?

For a simply supported beam with a length L and a point load P at one end, what is the reaction at the other end?

Step 1: Understand that a simply supported beam is supported at two points, one at each end.
Step 2: Identify that a point load P is applied at one end of the beam.
Step 3: Recognize that the beam will try to balance the forces acting on it.
Step 4: Since the beam is in equilibrium, the total upward reaction force must equal the total downward force.
Step 5: The only downward force is the point load P at one end.
Step 6: Therefore, the reaction force at the other end must be equal to P to keep the beam balanced.

Static Equilibrium – Understanding how forces and moments balance in a simply supported beam.
Support Reactions – Calculating the reactions at supports due to applied loads.
Beam Loading Conditions – Recognizing the effects of point loads on beam reactions.
