Caplets are used to support a sand core inside a sand mold cavity. The design of the caplets and the manner in which they are placed in the mold cavity surface allows each caplet to sustain a force of 45 N. Several caplets are located beneath the core to support it before pouring; and several other caplets are placed above the core to resist the buoyancy force during pouring. If the volume of the core = 5450 cm3, and the metal poured is steel, determine the minimum number of caplets that should be placed (a) beneath the core, and (b) above the core (Sand density = 1.6 g/cm3, steel density = 7.82 g/cm3).
A Midwest Cooperative needs to store 15 750 gallons of a liquid chemical. They are considering two possible containers, a hollow cylinder or a hollow sphere. The wall of the sphere will need to be 6 in. thick and the wall, top and bottom of the cylinder are each 6 in. thick. Due to space limitations the height of the cylinder must be 26.0 ft. (a)What will be the outside diameter of the cylinder required to hold the liquid chemical? (b)What will be the outside diameter of the sphere? (c)Assume the containers are made of aluminum, which container uses the most material?

Question 2 A proposed design for a part of a seawall consists of a rectangular solid weighing 860 N with dimensions of 14 m by 4.00 m by 2.00 m. The 14 m side is to be vertical. Will this object float stably in seawater? Show all calculations that lead to your conclusion.
In his experiment to test whether the crown of the King of Syracuse was made of pure gold or not, Archimedes immersed the crown into a container filled with water. He noted that the crown displaced 150 mL of water. If the mass of the crown is 2675 g, is it made of pure gold? A storage tank that is 15 m high is open at the top and initially filled with water. It developed a hole 12 m below the surface of water along its side. (a) What is the initial speed of water through the hole? (b) How far from the base of the tank will the water stream strike the ground?

The bottom plate is stationary and the velocity profiles for each fluid are linear. The top fluid (fluid 1), with a specific gravity of 0.8 and kinematic viscosity of 1.0 × 10“ m²/s, puts a shear stress on the upper plate. The lower fluid (fluid 2), with a specific gravity of 1.1 and kinematic viscosity of 1.3 × 10“ m²/s, puts a shear stress on the bottom plate. Determine the ratio of the shear stress on the top plate to the shear stress on the bottom plate. 3 m/s 0.010 m fluid 1 fluid 2 0.036 m 2 m/s Figure lb

Read the question carefully and give me right solution according to the question. Note : Figure not given. The top portion of an equilateral triangle is a light material (foam) with specific weight of 1.57 kN/m3. Compute for the height (in meters) of the bottom material if its specific weight is 20 kN/m3 and 20 cm of the foam is above the salt water (sg=1.03)?
can you help with prob num 1? with complete solution please and illustration thank youuu!
