(i) In what way does an ‘Ideal machine’ differ from a ‘Practical machine’? (ii) Can a simple machine act as a force multiplier and a speed multiplier at the same time? |
|
Answer» (i) An ideal machine is the one whose parts are frictionless as well as weightless, such that its mechanical advantage is equal to its velocity ratio. A practical machine is the one whose parts are neither frictionless nor weightless. Furthermore, its mechanical advantage is always less than its velocity ratio. (ii) No, it can be either speed multiplier or force multiplier. |
