What is the term for the type of load that is unchanging?

• A. Static loading
• B. Dynamic loading
• C. Cyclic loading
• D. Transient loading

Answer: (A)

When a load does not change with time, it is described as static loading. Static means the force has a constant magnitude and direction, like a dead weight sitting on a structure that doesn’t move. This is the term that best fits an unchanging load, because it implies no time variation. In contrast, dynamic loading involves forces that change over time, due to movement, acceleration, or impact. Cyclic loading is a type of dynamic loading that repeats over time, while transient loading refers to a temporary change that eventually moves back toward a steady state. These are not unchanging, so they don’t describe the situation as accurately as static loading.
