The small metal cylinder has a mass of 0.20 kgkg, the coefficient of static friction between the cylinder and the turntable is 0
.080, and the cylinder is located 0.15 mm from the center of the turntable 0.080, and the cylinder is located 0.15 mfrom the center of the turntable.Take the magnitude of the acceleration due to gravity to be 9.81 m/s2.
Lubricating a machine will make it more efficient and it will reduce the friction between the parts meaning that less energy will be transferred and dissipated into the surroundings as heat. the in put and out put force may increase as it's easier for the machine to work due to less friction
