Virtual work for BSC mathematics and statistics, virtual work for UPSC mathematics lecture 5

Four equal uniform rods, each of weight w, are freely jointed to form a rhombus ABCD. The frame work is suspended freely from A and a weight W is attached to each of the joints B, C, D. If two horizontal forces each of magnitude P acting at B and D keep the angle BAD equal to 120degree , prove that P=(W+w)2√3 Virtual Work in Engineering Mechanics | BSc Physics Statics | Principle of Virtual Work | Notes & Examples Learn the Principle of Virtual Work in Engineering Mechanics and BSc Physics (Statics).
