Option 3 : Point
Explanation:
Point load is that load which acts over a small distance. Because of concentration over small distance this load can may be considered as acting on a point. Point load is denoted by P and symbol of point load is arrow heading downward (↓).
Uniformly distributed load is that whose magnitude remains uniform throughout the length.
Uniformly Varying Load (Non – Uniformly Distributed Load): It is that load whose magnitude varies along the loading length with a constant rate.
Uniformly varying load is further divided into two types:
- Triangular Load: whose magnitude is zero at one end of span and increases constantly till the 2nd end of the span.
- Trapezoidal Load: which is acting on the span length in the form of trapezoid. Trapezoid is generally form with the combination of uniformly distributed load (UDL) and triangular load.
