Question

Sand falls on to a conveyor belt at a constant rate of 2kg/sec. If the belt is moving at 0.1m/sec. Then the extra force required to maintain speed of the belt is

Answer 1

Explanation:

Force generated due to falling of sand on the conveyor belt is

V

d

m

d

t

I.e

(

0.25

⋅

3

)

N or 0.75 N

So,this amount of force will be required per second to help per meter movement of the belt,hence extra power that would be required is

P

=

F

⋅

v

=

(

0.75

⋅

0.25

)

or 0.18 watt....

hope this will help you

thank you
