Adisc cam (with a base circle diameter of 100 mm) must produce a lift of 40 mm. this must occupy 90 degrees of rotation. the knife-edge follower then dwells at this level for 30 degrees, and the fall over the next 90 degrees. there is then 150 deg of rotation to complete the cycle. design a cam profile for constant velocity when rising and falling. if the velocity is 25 mm/sec, what must be the speed of rotation?

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
