Problem Statement A delivery truck of rectangular shape with a height of 10 ft a width of 85 ft and an estimated length of 6 m accidentally plunges into a freshwater lake of depth 10 m during a road accident The truck becomes partially submerged and comes to rest at an angle of 20 to the horizontal with the front end deeper than the rear The truck was loaded with 1500 kg of commercial goods and its curb empty weight is approximately 4500 kg The trucks cabin remains sealed initially but water gradually seeps in The driver trapped inside eventually manages to open the driverside door which has dimensions of 15 m height and 2 m width and is hinged at the front edge The door is made of a composite material and its mass is negligible compared to the water forces acting on it a Calculate the magnitude of the hydrostatic force acting on the door at the moment just before it was opened assuming the door is fully submerged Page 2 of 2 b Determine the center of pressure for the inclined door c Discuss in detail the conditions under which the driver was able to open the door incorporating pressure equalization moment analysis about the hinge and the effect of internal air compression or flooding d Compute the buoyant force acting on the truck using appropriate geometric approximations and determine the net force required to lift the truck vertically upward from the lake bottom considering submerged weight and full buoyancy Note You need to present your work in a standard report form prepared on MS word The report presentation carries 2 points Your report should be submitted on or before the due date No report will be accepted after due date
