a) Determine the shear force V and bending moment M at a cross section located 3.0m from the left-hand support.
b) Find the values of load P2 that results in V=0 at a cross section located 2.0m from the left hand support.
c)If P2=8kN, find the value of load P1 that results in M=0 at a cross section located 2.0m from the left-hand support.
