What is the formula for calculating the shear force at a section of a beam subjected to a point load?
V = P - w * x
V = w * x
V = P
V = P - M/L
The shear force V at a section of a beam subjected to a point load P and a uniformly distributed load w is given by V = P - w * x, where x is the distance from the load.

Q: What is the formula for calculating the shear force at a section of a beam subjected to a point load?
Solution: The shear force V at a section of a beam subjected to a point load P and a uniformly distributed load w is given by V = P - w * x, where x is the distance from the load.
Steps: 5
Step 1: Identify the point load (P) acting on the beam. This is the force applied at a specific point.
Step 2: Identify the uniformly distributed load (w) acting on the beam. This is a load spread evenly over a length of the beam.
Step 3: Determine the distance (x) from the point load to the section of the beam where you want to calculate the shear force.
Step 4: Use the formula V = P - w * x to calculate the shear force (V) at that section of the beam.
Step 5: Substitute the values of P, w, and x into the formula to find the shear force.
