Web2 days ago · In order to measure the energy dissipation due to friction in different cutting depths, the concept of friction work factor is proposed in this paper, which is the ratio of the specific energy corresponding to the work done by overcoming the friction force to the MSE, and it can be expressed as, (14) ξ = E M S E μ E = 1 F e μ F n + 1 where ... Webthat barely open and close, you know that a large part of your work is wasted overcoming the tightness, or friction, between the parts of the scissors • In every machine, some work is wasted overcoming the force of friction • The less friction there is, the closer the output work is to the input work • To calculate the efficiency of a ...
WebAug 1, 2024 · Solution 3. The reason you're finding this non-intuitive is because you're assuming that the applied force on the top block will cause the bottom block to experience the same force due to friction which is wrong. For example, consider two blocks A and B , sitting side by side on a smooth table. If you apply a force F on A, then one may ...
