hello every one i got that ques on my physics am abit struggling as i done it but my calculation comes with abit big numbers so i got confused if any one can help thanks as i have to hand it soon to my cute lady teacher thanks every one calculate the ststic and the dynamic coeffecient of friction for the interface between a block of aluminum and oiled surface given that normal force is 9.70 and the force to start moving it is 3.45n and last the force to keep it moving at constant velocity is 3.2n
Machines That Use Pneumatics
Normal force 9.7N., start move force 3.45NStatic coefficient (3.45/9.7) 0.356Dynamic coefficient (3.2/9.7) 0.33Both are rounded.
