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 ).

Question

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
).

hi, can you solve this ? A smooth circular hole at the bottom of a metal cylinder is 0.04 mm in diameter. Ethanol is filled into the cylinder until it drips from the hole. Since the surface tension of the ethanol wetting the metal at ambient temperature is 22.3 dyn / cm and its density is 0.789 g / cm3, what is the minimum height of the ethanol in the cylinder for dripping to begin?

Your calculation and explanation are helpful. Next, Calculate elastic modulusYour observation of the gluten-free pancakes shows that they are much softer. For that reason you only use a 0.7 kg weight. Now the height of the pancake stack decreases from its initial value of 55 mm to a final value of 46 mm. Use these measurements to calculate the elastic modulus of the pancakes. Express your answer in Pascals but without including the unit.Next, Calculating distance between bonds Given your measurement of the elastic modulus, what is the distance between the bonds in the gluten-free pancakes? Assume that the interaction energy between the molecules in the gluten free pancake recipe is Uint = kBT = 4*10-21J The cross link distance isa) larger than 1 micronb) between 100 nm and 1 micronc) between 10 nm and 100 nmd) between 1 nm and 10 nme) smaller than 1 nm
