Comparing torque/wrist force/comparing whose strength is greater - Science Museum exhibitions exhibition items plan
What It Shows
Rotate both sides vigorously and see how much strength you have! This demonstrates the principle of a lever, where the higher the ratio of resistance in the arm, the greater the force exerted. From ancient scrolls to modern cranes, it has been based on this principle. The effect of rotating an object is related to the magnitude of the force, not just the related force and direction. When the force of the rotating disc is the same size, the wheel diameter is larger, the arm is longer, the corresponding torque is larger, and the rotation efficiency is higher; The turntable has a small diameter and short arm, with low torque and poor rotation effect.
Science Behind It
The size of rotation and force not only affect the effect of an object, but also the direction of the force associated with the point of force. When the disks have the same size, larger disk diameter, long arm, and high torque force to rotate; With a small diameter disc, short arm, and low torque. source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. Prompt everyone to act on the axis perpendicular to the axis, rather than through the force axis generated by the torsional moment of the axis. The magnitude of this force is the product of the vertical distance of the axis. That is, F × R (F-force, R-handwheel radius), the torque generated by the force of the hand is 2F · R=F · d (D-diameter of the handwheel). It can be seen from the above that not only the magnitude of the torque and the force acting on the handwheel, but also the force on the diameter of the handwheel. When this force is constant, the torque generated by larger diameter handwheels also changes.
How to Operate
1. The participating audience stood on either side of the exhibits, twisted their respective wheels, and competed to see who had the greatest strength

Game Of Wrist Force
The effect of an object's rotation is related to action point and direction of an applied force besides to its magnitude. Production source factory of exhibits in science museum--Shanghai GuanLiang(inertia) Automation Co., Ltd reminds everyone that When apply a constant force on rotating a disk, the more diameter of the disk resulting in the larger arm of force and the greater moment,the higher rotation efficiency gained;it is the same the other way round.
