Answer / ankit jain
in is during ascending... Consider the following eqs.
During Ascending....
T - mg = ma
so T= m(g+a)
During descending....
mg - T = ma
so, T = m(g -a)
and since the lift will have to balance the tension in the rope alone, so T will be higher in the case of ascending lift.

Answer / sam
maximum load on lift will be more during ascending since
during descending it wll be regenerative breaking.

Answer / parthiban . r
though theortically its true, if we think its going to be
descending the reason is the force of body falling down
will be comparitively more
for example: you could find it easily by following
throw a ball over a person in upstairs and then do with
person in downstairs from up
definetly the person at downstairs will get more pain than
upstairs
so a small amount of load will be more than that of
ascending.

Greetings This question is about hydraulics and I request an expert to answer it. A simple hydraulic machine is made up of two heads, a larger one with a larger force inside a wider pipe and a smaller one with a smaller force inside a smaller pipe in width as in the second picture on this link: http://science.howstuffworks.com/hydraulic1.htm The question is this: what happens if the smaller head and the smaller force doesn’t exist but the smaller pipe is high enough to take all the liquid? For example the larger head is 1.00 sqr metre and can go down 1.00m under a weight of 100.00kg. The cross sectional area of the smaller pipe is 0.001 sqr metre. Now when the larger head goes down 1.00m, how high the liquid from the wider pipe can go into the smaller pipe of the cross sectional area of 0.001 sqr metre? Regards
