All forces and torques on a small section of plate with an arbitray load: | ||||||||||
q(x) --- downward force per unit length exerted on the plate V --- a net shear force per unit length, act on the cross section of plate normal to plane of the figure w --- deflection at the point x M --- the net bending moment P --- horizontal forces on the segment that act with a net lever arm length of dw to produce a torque of -P.dw |
