3 cards from this section. Quick, good the night before a test.
What direction is a positive load on a beam?
Think of 'up' as positive in everyday terms.
What type of axial force is considered positive?
Recall that tension pulls on the beam.
What convention defines a positive load?
Remember the right-hand rule.
True or False? Tension is classified as a negative axial force.
Always consider forces that pull to be positive.
Consider a beam subjected to a point load at one end and a uniformly distributed load along its length. Analyze the shear force and flexural moment at different points of the beam.
Utilize the relationships defined in the section to deduce shear and moment.
A cantilever beam is fixed at one end with a downward load applied at the free end. Calculate the flexural moment at the fixed support.
Remember: Moment = Force x Distance.
