Acrowbar 2727 in. long is pivoted 66 in. from the end. what force must be applied at the long end in order to lift a 600600 lb object at the short end?

To solve this problem we will apply the concepts related to equilibrium, for this specific case, through the sum of torques.

If the distance in which the 600lb are applied is 6in, we will have to add the unknown Force sum, at a distance of 27in - 6in will be equivalent to that required to move the object. So,

So, Force that must be applied at the long end in order to lift a 600lb object to the short end is 171.42lb

i think the answer would be b

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
