Part 1
The storage tank contains lubricating oil of specific gravity 0.86 In one inclined side of the tank,
there is a 0.48 m diameter circular inspection door, mounted on a horizontal shaft along the centre
line of the gate. The oil level in the tank rests 8.8 m above the mounted shaft. (Please refer table
01 for relevant SG, D and h values).
Describe the hydrostatic force and centre of pressure with the aid of a free body diagram of the
inspection door.
Calculate the magnitude of the hydrostatic force and locate the centre
of pressure.

- A virtual experiment is designed to determine the effect of friction on the timing and speed of packages being delivered to a conveyor belt and the normal force applied to the tube. A package is held and then let go at the edge of a circular shaped tube of radius R = 5m. The particle at the bottom will transfer to the conveyor belt, as shown below. Run the simulations for μ = 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6 and determine the time and speed at which the package is delivered to the conveyor belt.
