Find support reactions at A and B and then calculate the axial force N. shear force J and bending moment M at mid-span of AB. Let L = 14 ft. q0 = 12 lb/ft. P = 50 lb. and = 300 lb-ft.
You need to calculate support reactions at
The external reaction forces are
Given Information:
You have a beam with different types of loading as shown in figure below.
Figure 1 It is given that,
