A pulley system with a mechanical advantage of 15 is used to lift a 1750 N piano to a third floor balcony that is 7 m above the

devlian [24]

Answer:

The force is $E = 117 \ N$

Explanation:

From the question we are told that

The mechanical advantage is $ME = 15$

The load is $L = 1750 \ N$

The height is $h = 7 \ m$

Generally mechanical advantage is mathematically represented as

$ME = \frac{L }{E }$

Here E is the force that must be applied to move the piano

=> $E = \frac{L}{ ME }$

=> $E = \frac{1750 }{15 }$

=> $E = 117 \ N$

Type the correct answer in the box. Round your answer to the nearest whole number. Calculate the man’s mass. (Use PE = m × g × h

Blababa [14]

Answer:

56 kg

Explanation:

The change in potential energy of the man is given by:

$\Delta U = mg \Delta h$

where

m is the man's mass

g is the gravitational acceleration

$\Delta h$ is the change in height of the man

In this problem, we have:

$\Delta U=4620 J$ is the gain in potential energy

g = 9.8 m/s^2 is the gravitational acceleration

$\Delta h=8.4 m$ is the change in height

Re-arranging the equation and substituting the numbers, we find the mass:

$m=\frac{\Delta U}{g\Delta h}=\frac{4620 J}{(9.8 m/s^2)(8.4 m)}=56 kg$
