Question

The unbalanced vertical force, which tends to slide one portion of the beam upward or downward, is called as

• A. Body force
• B. Shear force
• C. Reactive force
• D. Bending force

Answer 1

Answer:

B. Shear force

Shear force is the resultant transverse force either from the left or right of the section. Due to this resultant or unbalanced force, the portion of beam tends to slide upward or downward based on the value of force. Clockwise shear is considered positive and counter-clockwise is negative. Bending moment produces sagging (positive) or hogging (negative) based on the concavity of the beam.
