Answer:
The crate rises up 25 cm.
Explanation:
It is given that,
Weight of crate, W₁ = 100 N
A woman lifts a crate by pulling a rope downward with a force of, W₂ = 25 N.
For every 1 meter length of rope she pulls downward, the crate rises.
d₁ = ?
d₂ = 1 m = 100 cm
It can calculated by using by the following relation :
W(input) = W(output)
[tex]F_1d_1=F_2d_2[/tex]
[tex]d_1=\dfrac{F_2d_2}{F_1}[/tex]
[tex]d_1=\dfrac{25\times 100}{100}[/tex]
d₁ = 25 cm
Hence, for every 1 meter length of rope she pulls downward the crate rises upto 25 cm.
A pulley is a wheel on an axle or shaft that supports the movement and direction changing of a taut cable or belt. The crate rises up to 25 cm.
A pulley is a wheel on an axle or shaft that supports movement and direction changing of a taut cable or belt, as well as power transfer between the shaft and the cable or belt.
The forces are balanced in nature. That's why the work done by both forces is the same
W₁=W₂
F₁d₁=F₂d₂
[tex]\rm d_1=\frac{F_2d_2}{F_1} \\\\ \rm d_1=\frac{100 \times 25}{100} \\\\\ \rm d_1=25N[/tex]
Hence the crate rises up to 25 cm.
