A cantilever is loaded as in the following sketch: P W B C D 1m 1m 3m P 1.5m E where P= 70 N and w= 40 N-m¹ References Section Break value: 2.77 points Difficulty: Medium Check all of the following statements that are true regarding the shear and moment diagrams for the given problem. (You must provide an answer before moving to the next part.) A point load downward causes a jump in the shear downwards. A uniformly distributed load causes a linear shear diagram. A triangular load causes a quadratic/parabolic/curvy shear diagram. Positive shear increases moment in a positive direction. A linear shear diagram causes a quadratic/parabolic/curvy moment diagram. A quadratic/parabolic/curvy shear diagram causes an even more curvy cubic moment diagram. A concentrated moment causes a jump in the moment diagram.
