Mechanical knowledge

A grid-based notebook page with handwritten and printed text and diagrams in purple borders. Title at top reads Statics of Rigid Bodies. Upper left section shows resultant force vectors forming a triangle with labels F1, F2, FR, and equations like sin = F1/FR, cos = F2/FR. Upper right illustrates equilibrium of forces with sum F_x=0, sum F_y=0, sum M=0. Middle left depicts parallelogram law with vectors F1, F2, R at angles. Middle right shows moment of force as M = F x d with a force perpendicular to a beam. Lower left has couple forces with two parallel forces creating torque. Lower right includes truss analysis using method of joints with pin connections and forces, and method of section cutting through members with free body diagram showing tensions and pulley with force N and tension T.
