A base of a box is 12 inches by 10 inches. It weighs 360 lbs. What is the pressure exerted on the floor by the box in Pascal unit? note: write only in your answer the value or magnitude (rounded off into a whole number). Do not include the unit.

A company has several sensors in storage silos to detect the total pressure in the silos to ensure the tanks will not leak. Each tank is designed to withstand a maximum total pressure of 5.7 atmospheres​ [atm]. An engineer wants to use one of the silos to store liquid nitric​ acid, which has a density of 97​ pound-mass per cubic foot [lbm​/ft3​]. If the tank is filled to a depth of 90 feet​ [ft], how much surface pressure in units of atmospheres​ [atm] can be applied to the top of the liquid inside the tank without exceeding the maximum total pressure of the​ silo?

A rectangular solid made of aluminum has a density p= 2.70 g/cm³. The dimensions of the solid are shown below. The solid is placed on top of a truncated cone whose circular ends have the dimensions shown. The bottom of the rectangular solid down on the top surface of the cone. Find the pressure (in N/m²)between those two surfaces. (Ignore air pressure.) (1 kg = 1000 g, 1 m 100 cm) presses 10.0 cm 8.00 cm 15.0 cm r= 2.00 cm R = 6.00 cm

The plug has a diameter of 30 mm and fits within a rigid sleeve having an inner diameter of 32 mm. Both the plug and the sleeve are 50 mm long. The plug is made from a material for which E= 1 MPa, v=0.7. (Figure 1) Figure Part A Determine the axial pressure p that must be applied to the top of the plug to cause it to contact the sides of the sleeve. Express your answer to three significant figures and include appropriate units. HA P= Submit Part B Value 8 = Request Answer Also, how far must the plug be compressed downward in order to do this?
