Questions & Step-by-Step Solutions
What is the formula for calculating the shear force in a beam at a distance 'x' from the left support?
Step 1: Identify the left support of the beam and label it as point A.
Step 2: Determine the reaction force at the left support (R). This is the force that supports the beam at point A.
Step 3: Identify the uniform load (w) acting on the beam. This is the weight distributed evenly along the length of the beam.
Step 4: Measure the distance (x) from the left support (point A) to the point where you want to calculate the shear force.
Step 5: Calculate the total load acting on the beam up to the distance x. This is done by multiplying the uniform load (w) by the distance (x): wx.
Step 6: Use the formula for shear force: V = R - wx. Here, V is the shear force at distance x, R is the reaction force at the left support, and wx is the total load up to distance x.
