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 ❤️❤️
A᭄nswer:-
──────────────────➤
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.
