Question 275978
A screwdriver 9in.long is used to open a can of paint. The tipof the screwdriver is placed under the lip of the lid with the fulcrum 0.15in. from the lip. A force of 30lb is applied to the other end of the screwdriver.Find the force on the lip of the lid

The formula for a lever is 
load * distance on one side = load * distance on the other side of the fulcrum

Let the load on the lid be x

x*0.15 = 30* 8.85

0.15x=265.5

x= 265.5/0.15
x= 1770 lbs.
