Dynamic Loading: Definition, Examples, and Causes

By BYJU'S Exam Prep

Updated on: September 25th, 2023

Before understanding dynamic loading, it is essential to understand load. The force exerted on a surface or body is referred to as the load in engineering.  A dynamic load changes regularly, such as the effect of people leaping up and down in a cable car. These modifications can be either random, periodic, or a combination.

Dynamic loadings are defined as varying loads frequently generating stronger forces than static loads. various dynamic loads: simple harmonic, non-harmonic, periodic, and non-periodic (short & Long duration). Let’s take a deep dive into the concepts of Dynamic Loading.

Dynamic Loading

A dynamic load is one that changes regularly, such as the effect of people leaping up and down in a cable car. Dynamic loading can be used to formulate the MSQ-based questions in the GATE ME question paper.

Dynamic Loading Definition

“Dynamic load is the load the actuator sees when it is powered and extending or retracting. The dynamic load capacity of an actuator refers to how much the actuator can push or pull.”

These modifications can be either random, periodic, or a combination. Dynamic loads are defined as varying loads that frequently generate stronger forces than static loads.

What is a Dynamic Load, and What Causes it?

Any load that changes over time is referred to as a dynamic load. These loads apply forces to buildings frequently substantially larger than their static equivalents. For example, someone leaping up and down will exert more force on the floor than someone standing still.

Dynamic loading can be caused by anything from individuals moving around to wind blowing on a structure or objects vibrating due to an earthquake.

Examples of Dynamic Loading

Let us now see a few examples of the dynamic loading important for the GATE exam and understanding the concept better.

  • Dynamic loads, from our homes and workplaces to bridges, roadways, and furniture, may be found everywhere.
  • The wind blows over a bridge while cars drive across it.
  • Dynamic loading can also be seen in conjunction with static loadings, such as with a crane, whose cab is a static load, while whatever weight is being hoisted can exert a dynamic loading force at the same time.

Difference between Static and Dynamic Loading

The most basic distinction between static and dynamic loads is that static loads do not move while dynamic loads do. A static load is also significant for the GATE ME syllabus. Static load in the supply chain is a loaded pallet on the floor, whereas a dynamic load is a loaded pallet being moved by a forklift, pallet jack, or other equipment.

Mode of Failure

A mechanical component failure can occur as a result of any of the following failure modes:

  • Elastic deflection failure
  • General yielding failure
  • Fracture-based failure
