To solve the problem step by step, we will follow the given information and apply the relevant formulas. ### Step 1: Understand the setup We have a crowbar that is 2 meters long, and it is pivoted 10 cm (0.1 m) from its tip. This means the distance from the pivot to the load (load arm) and the distance from the pivot to where the effort is applied (effort arm) needs to be calculated. ### Step 2: Calculate the load arm The load arm is the distance from the pivot to the point where the load is applied. Since the crowbar is 2 m long and the pivot is 0.1 m from the tip, the load arm can be calculated as: \[ ...
