Metal Bracket Bottom Plate with Single Pulley for Physics Mechanics Experiments – Compatible with Standard Teaching Kits

Metal Bracket Bottom Plate with Single Pulley for Physics Mechanics Experiments – Compatible with Standard Teaching Kits Description

Specification: Size: bottom plate length 160* bottom plate width 100* bracket height 320mm Pulley diameter: 30mm/40mm Cord length: 68cm/100cm Material: metal, plastic Weight: about 550g Uses: It is suitable for mechanics and students' group experiments. *The pulley block and bracket are suitable for physical mechanics and student group experiments *The instrument is mainly composed of a metal base plate, a metal support rod, two single pulleys and two series double pulleys. *It consists of 2 strings with hooks (length 100cm/short 68cm), etc. It shows that moving the pulley can save half the effort, but it cannot change *Fixed Pulley: hang one fixed pulley on the bracket, put on the rope, hook one end to the hook code, and the other end to hook the dynamometer. Pull the dynamometer with your hand at a constant speed, and you can observe that the indication of the dynamometer is equal to the weight of the hook. It is stated that the fixed pulley is not labor-saving, but the direction of use can be changed. *Moving Pulley: first measure the weight of a single pulley with a dynamometer, then hang a hook on the hook of the pulley, tie the rope end to the bracket, and connect the other end to the dynamometer after passing through the pulley, and pull upward at a constant speed to measure the force It can be observed that the indication value of the dynamometer is equal to half of the total weight of the pulley and the hook.
