What distinguishes a pin support from a roller support?
A pin support allows for vertical movement, while a roller does not.
A pin support prevents rotation, while a roller allows it.
A pin support allows for vertical movement, while a roller restricts it.
A pin support restricts movement in both vertical and horizontal directions, while a roller allows horizontal movement.

Loads that are only considered in two-dimensional structures
Loads that include dead loads, live loads, and environmental loads
Why is it crucial to follow codes and standards during structural analysis?
To reduce the overall cost of construction
To guarantee the structural integrity and safety of the design
To simplify the calculations involved
To ensure the design is visually appealing

Which type of load is best represented by a concentrated load in structural analysis?
A uniform load distributed over a large area
A load that varies in magnitude along a length
A load applied at a single point
A load that acts over a surface area
When analyzing a structure, why is it important to make idealizations?
