POTENTIAL ENERGY AND ENERGY CONSERVATION 7 7.1. IDENTIFY: U grav = mgy so ΔU grav = mg ( y2 − y1 ) SET UP: + y is upward. EXECUTE: (a) ΔU = (75 kg)(9.80 m/s 2 )(2400 m − 1500 m) = +6.6 × 105 J (b) ΔU = (75 kg)(9.80 m/s2 )(1350 m − 2400 m) = −7.7 × 105 J EVALUATE: U grav increases when the altitude of the object increases. 7.2. IDENTIFY: The change in height of a jumper causes a change in their potential energy. SET UP: Use ΔU grav = mg ( yf − yi ). EXECUTE: ΔU grav = (72 kg)(9.80 m/s2

Clutch Objective: The Aim of this experiment is to find the relation between the axial load W and the frictional torque T‚ using a single plate clutch. To find the coefficient of friction between the clutch surfaces using the uniform wear theory. To experimentally conclude whether the average radius of the friction plate is proportional to the frictional torque. Apparatus used: Weights‚ String Plate clutch Hangers Pulleys 5 x 2kg weights for axial load Theory: It is stated theoretically

force of 95.0 N is applied to a 60.0-kg crate on a rough‚ level surface. If the crate accelerates at 1.20 m/s2‚ what is the magnitude of the force of kinetic friction acting on the crate? (a) 23.0 N (b) 45.0 N (c) 16.0 N (d) 33.0 N (e) 8.80 N Newton’s second law gives the net force acting on the crate as This gives the kinetic friction force as ‚ so choice (a) is correct. 2.

particle. However‚ the most widely used version is the singleface design. ABOUT ELECTROMAGNETIC CLUTCH These electromagnetic clutches are designed to have a very high torque to size ratio. They include longlife friction materials‚ are corrosion protected and require little or no maintenance after installation. Typical applications include copiers and printers‚ packaging and labelling machinery‚ medical equipment‚ conveyors‚ document feeders and textile machinery

A hockey stick exerts an average force of 39N on a 0.2kg hockey puck over a displacement of 0.22m. if the hockey puck started from rest‚ what is the final velocity of the puck? Assume no friction. Your physics teacher walking with the aid of a cane approaches a skateboard of 3.5 kg lying on the side walk. Pushing with an angle of 60 degree down from the horizontal with his cane‚ he applies a force of 115N‚ which is enough to toll the skateboard out of his way. Calculate the initial acceleration
