How to calculate using counter balance to lift a mass from undersea to above seawater.
A huge beam planted into sea and the height 15meter above seawater. Total length 30m. Using pulley system, both side left and right hung 2 equal weight drum. The whole picture should be similar to Elevator method
Question: How counterbalance and pulley system calculation will be? Do I need to consider buoyancy formula and also F=ma.
