Define the following terms with reference to a machine (a) Total load

1.	Define the following terms with reference to a machine (a) Total load (b) useful load (c) effort (d) ideal machine (e) ideal mechanical advantage (f) actual mechanical advantage (g) velocity ratio (h) efficiency.
Answer» (a) Total load : Load lifted by machine + resistance over come. (b) Useful load : “The load, a machine in able to lift.” (c) Effort : The effort applied by us on the machine. (d) Ideal machine : A machine whose parts are weightless and frictionless such that what so ever is the energy spent on it same is the energy produced by it, is called a perfect machine.” (e) Ideal mechanical advantage : “The ratio between total load moved (or resistance overcome) to the effort applied is called ideal mechanical advantage.” (f) Actual mechanical advantage : “The ratio between useful load moved to the effort applied is called actual mechanical advantage”. (g) Velocity ratio : [V.R.] : “Is the ratio of velocity of effort to velocity of load.” i. e “Ratio of effort arm to load arm.” (h) Efficiency : (η) “Efficiency of a machine is the ratio of useful work done by machine to the work put into the machine by the effort.”

Answer»

(a) Total load : Load lifted by machine + resistance over come.

(b) Useful load : “The load, a machine in able to lift.”

(d) Ideal machine : A machine whose parts are weightless and frictionless such that what so ever is the energy spent on it same is the energy produced by it, is called a perfect machine.”

(e) Ideal mechanical advantage : “The ratio between total load moved (or resistance overcome) to the effort applied is called ideal mechanical advantage.”

(f) Actual mechanical advantage : “The ratio between useful load moved to the effort applied is called actual mechanical advantage”.

(g) Velocity ratio : [V.R.] : “Is the ratio of velocity of effort to velocity of load.” i. e “Ratio of effort arm to load arm.”

(h) Efficiency : (η) “Efficiency of a machine is the ratio of useful work done by machine to the work put into the machine by the effort.”

Define the following terms with reference to a machine (a) Total load (b) useful load (c) effort (d) ideal machine (e) ideal mechanical advantage (f) actual mechanical advantage (g) velocity ratio (h) efficiency.
