In lifting a 30 Kg container with a class 1 lever, it is noted that for every 2 m distance input the lever pushed down, the container rises 1 m. (Assuming no friction) 1. Draw the case described above and label the input and output forces and distances. 2. What is the mechanical advantage of the lever? 3. Find the input force.
