measure the torque applied to the system. The speed of the motor and the torque applied is displayed digitally on digital meter. The speed of the ring gear of the first stage epicyclic gear system is measured by using an inductive proximity sensor. This speed is displayed on a digital rpm meter. Pulley system and spring load is connected at the end of the third stage epicyclic gear system to measure the output torque. With the results obtained‚ the characteristic (speed and torque) of an epicyclic

the role of a good impact wrench delivering high torque required to work with nuts‚ bolts‚ and sockets with minimum effort. It improves maximum efficiency and reduces fatigue and serves as a staple for all kinds of mechanics. The excellent feature about this Ingersoll rand cordless impact wrench is that it has the ability to generate a huge amount of torque. This Ingersoll’s rand cordless impact W7150 is designed to produce 1100 feet-lbs of torque which is more than enough for handling lots of automotive

consequence of assumed uniform wear leads to a simple theoretical expression for the torque transmitted by a plate clutch just before slip occurs. It is evident that this must depend on the friction between the plate and the plate it presses on. Hence this experiment uses three different sizes of friction plates to test the theory and assumption. 2. THEORY Consider an upper turntable which turns due to the torque T on a concentric friction plate supported by a stationary base. The inner and

Theory 2.1 Introduction A gear train is two or more gear working together by meshing their teeth and turning each other in a system to generate power and speed. It reduces speed and increases torque. To create large gear ratio‚ gears are connected together to form gear trains. They often consist of multiple

The length-tension relationships represent an important part in the function of skeletal muscle. When skeletal muscle is stimulated‚ passive tissue rapidly changes into dynamic tissue which can produce force. Furthermore‚ during this process‚ the length of muscle may decrease‚ increase‚ or remain the same. Moreover‚ the amount of power a muscle can produce depends on its length‚ velocity and stimulation Powers & Howley (2015). Muscle velocity and stimulation are normally in a constant when creating
