Product Code : SCL-FAM-14594
Indian Lab Suppliers supplies the Parallelogram Law Apparatus | Gravesande (Product ID: 14594) as part of its forces and motion range. It verifies the parallelogram law of forces with two pulleys, hanging weights and a vertical drawing board.
Quick Answer
Two pulleys at the top of a vertical board carry cords with weight hangers, and a third load hangs from the knot joining the cords. When the knot comes to rest, the two cord tensions, drawn to scale along the cords as adjacent sides of a parallelogram, give a diagonal equal and opposite to the third weight. The board is about 450 × 600 mm, in graph or plain finish, on a wooden or powder-coated metal base. Pulleys are aluminium or brass with ball bearings, and the cords are smooth nylon.
