# variation

posted by .

the load which a crame can lift up is directly proportional to the mass and inversely proportional to the height through which the load is to be lifted.if a load of 40 and mass of 175gm is lifted through height of 286m,from what load will be carried through height 50m given the mass as 250gm?

• variation -

"variation" is not your school subject. This looks like physics. For all I knew, you could have been asking about the variation of terrain in the Sierra foothills or the variables in a public opinion survey - anything.

Finally! Your variation description says that

L = km/h
so, Lh/m = k is constant. So, you want L such that

L*50/250 = 40*286/75
