A frame supports both a linear distributed load and a concentrated moment, as shown in the figure below. The
distributed load has a magnitude qo = 140 N/m at point B which decreases linearly to zero at point C. The
concentrated moment has a magnitude Mc = 79 N - m and acts at point C. The frame is held in equilibrium
by a pin at point A and a cable BD. The horizontal and vertical dimensions are given as: L₁ = 7 m, L₂ = 1.5 m
, and L3
13 m. Neglect the thickness and weight of the frame for this analysis. Determine the internal
normal force (P), internal shear force (V), and internal bending moment (M) at the following locations:
