Static and Dynamic load
What are Static and Dynamic load and what are their significant dynamic effects?
Expert
Static load is the load in which force direction will remain constant with the time. Normally static load is the effect of gravity on an object or structure. Yielding is the main cause for the failure in the case of static loading. The example of static loading is weight of bridge.
Dynamic load is the force or load that changes its direction with the time. There are many examples like force of wind on a shining board, load on the rotating unbalance rotor or load of vehicle on the bridge. First and third case is not the periodic loading while second case is the example of periodic dynamic loading.
These are loads that display significant dynamic effects. Examples include impact loads, waves, wind gusts and strong earthquakes. Because of the complexity of analysis, dynamic loads are normally treated using statically equivalent loads for routine design of static structure. This is the graphical representatio:
The main cause of disk of turbine gas engine is dynamic loading only. Brittle material shows poor strength against dynamic load. Army never march on the bridge. This is also because of dynamic loading. Failure mechanism is crack propagation. Crack initiates and grow with the dynamic load.
Water flowing via the vertical pipe is illustrated below. Compute the required pipe diameter for the smaller pipe,‘d’, given that the two pressure gauges read similar value. Q : Product performance in Product design Product performance: Depending on the product, this may take many forms. Speed, loads to be withstood, number of work cycles, and intermittent or continuous working are some examples of considerations.
