Elastic nut is a locking device in which

One small nut is tightened over main nut and main nut tightened against smaller one by loosening, creating friction jamming

Hard fibre or nylon cotter is recessed in the nut and becomes threaded as the nut is stewed on the bolt causing a tight grip

Through slots are made at top and a cotter pin is passed through these and a hole in the bolt, and cotter pin splitted and bent in reverse direction at other end

A slot is cut partly in middle of nut and then slot reduced by tightening a screw

Machine Design
When a shaft is subjected to combined twisting moment (T) and bending moment (M), then the equivalent twisting moment is equal to

√(M² + T²)

(1/2) × √(M² + T²)

M + √(M² + T²)

(1/2) × [M + √(M² + T²)]

√(M² + T²)

(1/2) × √(M² + T²)

M + √(M² + T²)

(1/2) × [M + √(M² + T²)]
