4. In a single-acting, two-stróké, opposed atio of the masses of the top piston and its connected moving arts to the bottom piston and its moving parts, is 7-5 to 6, and he strokes of the pistons are in inverse ratio to their masses. The combined stroke of the top and bottom pistons is 2430 mm. The engine has six cylinders of 625 mm diameter and the indicated nean effective pressure is 6-5 bar when running at 1-75 rev/s. Assuming a mechanical efficiency of 90%, find the strokes of the op and bottom pistons, the indicated power and the brake power.
