Question

calculate the mechanical advantage of a crowbar of length 360 CM if its pulchrum is situated at a distance of 60 cm from the load​

Answer 1

Length of crowbar = 360 cm Length of load arm = 60 cm Length of effort arm = 360 cm – 60 cm = 300 cm Mechanical=load/effort

so

300/60

5 is the answer ❤️❤️

Answer 2

──────────────────➤

Step-by-step explanation:

Given that,

Length of the crow bar is 360 cm

Its fulcrum is situated at a distance of 60 cm from the Load. Its load is 60 cm.

To find,

The mechanical advantage of a crow bar.

Solution,

The ratio of effort arm to the load arm is called mechanical advantage of a crowbar. In this case, effort arm is equal to 360 cm - 60 cm = 300 cm.

Mechanical advantage is therefore given by :

m= 300/60

m=5

So, the mechanical advantage of a crow bar is 5.

This is your answer.
