Spring Balancer is a device to suspend machines and equipment. The tension is kept stable on even if the cable is pulled out or retrived because of the tapered drum. Main uses of spring balances are to weigh heavy loads such as trucks, storage silos, and material carried on a conveyor belt. They are also common in science education as basic accelerators. They are used when the accuracy afforded by other types of scales can be sacrificed for simplicity, cheapness, and robustness.
Spring balances consist of a cylindrical tube with a spring inside. One end (the top) is usually fixed to an adjuster which can be used to calibrate the device. The other end is attached to a hook on which you can hang objects. Spring balance is used to measure the weight of the body whereas beam balance is used to measure the mass of the body. Since the mass of the body remains the same on earth as well as on moon but the acceleration due to gravity differs.
A spring balance is simply a type of weighing scale used to find the weight of an object. This type of balance works on the Hooke’s law. According to Hooke’s law, force required to elongate or compress is directly proportional to the amount of the elongation or compression occurred in the spring.
