Question: What is the shear force at a section of a simply supported beam just to the left of a point load?

Options:

Correct Answer: P

Solution:

The shear force (V) just to the left of a point load (P) on a simply supported beam is equal to V = P.

What is the shear force at a section of a simply supported beam just to the left of a point load?

Step 1: Understand that a simply supported beam is supported at two points and can carry loads in between.
Step 2: Identify the point load (P) acting on the beam. This is the force applied at a specific point.
Step 3: Recognize that shear force (V) is the internal force that acts along the beam to keep it in equilibrium.
Step 4: Focus on the section of the beam just to the left of the point load (P).
Step 5: Realize that the shear force just to the left of the point load is equal to the magnitude of the point load itself.
Step 6: Conclude that the shear force (V) just to the left of the point load (P) is V = P.
