3. A papercip made of steel wire (psteel-7500 KE/m3) floats in water supported by surface tension (o-0.073 N/m). This paperclip has length =50 mm, cross-section diameter 1.5 mm and perimeter 103 mm. If the manufacture products the same paperclip with silver (P silver 10490 Km), will it be able to float in water with the same surface tension? Please show the calculation to support your answer.

Questiorn If the surface tension of water is 0.0728, what is the capillary rise (in meters) in a glass tube that is 1.0 mm in radius? Your answer should have two significant figures. Use Pwater 1.0for the density of water. 0 for the density of water cm Use98for the acceleration due to gravity. Assume the contact angle, θ is equal to 0 . . Provide your answer below:

A long slender solid cylindrical rod made of copper is 2 cm in diameter. It is taken out of a liquid nitrogen bath at 77 K and exposed to a stream of warm air at a temperature of 50 C. Neglect internal temperature gradients find the time taken by the rod to heat up to a temperature of 10 C if the surface heat transfer coefficient is 20 W/m^2K. For copper, take k=330 W/mK and ?=95*10^-6 m^2/s.

- 10 cm Problem 4 A l-m diameter cylindrical container contains a liquid with a specific gravity of 1.2 to a depth of 0.50 m. A cube of wood which is 10-cm on each side and with a density of 700 kg/m is placed in the cylinder as shown. Determine (a) what percentage of the cube is submerged; and (b) the new depth of liquid, h, in the container. 10 cm NOT TO SCALE
Problem 1. A cylindrical pressure vessel has inside diameter d_{o} = 500 mm and inside diameter di=490 mm.if it i made of carbon steel SAE 1040 OQT1300, find the maximum allowable internal pressure if the safety factor against yielding is not to be less
Problem 1.A cylindrical pressure vessel has inside diameter d_{o} = 500 mm and inside diameter di=490 mm.if it i made of carbon steel SAE 1040 OQT1300, find the maximum allowable internal pressure if the safety factor against yielding is not to be less than 4. Neglect the external pressure and assume that the longitudinal stresses are taken by the vessel itself.a) Solve using the MSST. b) Solve using the DET.See Appendix 3 for material properties.
