For the determination of potential Energy of a Weight. Bench top unit for experiments on mechanical work and potential energy the work necessary to be applied to lift a given load using varying force is determined.

• Including strong metal plate as experiment carrier, lever mounted in a bearing weight hung on the lever.
• Lifting a weight using a lever and a spring balance, spring balance is attached perpendicular to the lever measuring: 0...25N, lifting sets a tensile force and thus deflects the lever.
• Integrated angle measuring scale on plate to measure lever deflection. Set of weights: 4x 5N, 4x 1N, 1x 1N, hanger. w x d x h: 530x350x640mm; Englishoperation / instruction manual.

Bench top unit for investigation of spatial equilibria of forces, vector addition and resolution, consisting of:

• tension chain with integrated dynamometer to be connected with top of the push rods,
• moveable mounting for other end of tension chain
• set of weights as load to be connected with hook at top of the pushrods
• Angles to be adjustable by changing the lengths of the rods and the chain complete with steel base plate. w x d x h:± 1000x565x500mm
• English operation / instruction manual.
