A lever is 3.2 m long. The distance from the fulcrum to the underside of a boulder to be lifted is 1.4 m. If a farmer pushes on the opposite end with 350 N, what is the maximum force that is applied to the boulder

The value is        

Explanation:

From the question we are told that

    The force applied at the other end is  

    The length of the lever is  

     The distance from the fulcrum to  the underside of a boulder is

      The distance from the fulcrum to the point where the farmer applied the force is  

=>        

Generally at equilibrium the net torque experienced by the lever is  0 and this is mathematically represented as

Here W is the maximum force applied to the boulder by the lever

So

=>      

=>              

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

in this image, you can see solar radiation going through ocean water.
