The image below shows a typical laboratory equipment found in some universities. The goal is to measure the hydrostatic force acting on the flat side of the circular arc block and compare it to the theoretical value for a given depth h. The counterweight is arranged so that the pivot arm is horizontal when the block is not submerged, hence the weight W can be correlated with the hydrostatic force when the submerged arm is again brought to horizontal. Do the hydrostatic forces need to be taken into consideration if we take moments at the pivot? Explain.

Please solve this question. Subject: Transportation engineering Problem No.2 Fillet Radius Problem (Airport Engineering) Determine the minimum lead-in and the radius of the fillet to maintain the cockpit over the centerline for an aircraft with a 200.4 ft wingspan (i.e. airplane design group V), a wheelbase of 90.5 ft, undercarriage width of 41.3 ft, and the distance between the main undercarriage and cockpit equal to 95.3 ft. The aircraft is moving between two parallel taxiways through a connecting taxiway which has a centerline perpendicular to the parallel taxiway. (Assume taxiway width is 75 ft, the minimum safety margin is 15 ft, centerline radius is 150 ft).
