A steel sheet with dimensions LxWxH = 50 mm x 10 mm x 2 mm is to be coated with a thin layer of nickel using electroplating. The sheet is entirely submerged in the electrolytic bath for 15 mins. If the process operates at a current of 80 amps, determine the average plating thickness. Which electrode should the steel sheet act as?

1. You have a sheet of carbon steel with a thickness of 1 mm, a length of 300 mm, and width of 150 mm. You are testing it in a furnace that is flowing hot air over the sheet at 3 m/s at T 1 300 K along the length of the metal. The carbon steel is initially at 300k and has the following properties p 7850 R/ C 430 //kok, and R, 1490 W/mK. The carbon steel is sitting...

Question 2 (30 marks) The wood beam below (cross section dimensions 150 x 250 mm, as indicated) is strengthened at the bottom using 3 steel reinforcement plates of the same 12mm thickness (see figure), perfectly glued to the wooden beam. The modulus of elasticity for wood is E,-12 GPa and for steel E,-200 GPa. Given the allowable stresses (in both tension and compression) for wood ơw-12 MPa and for steel Ơs = 150 MPa, determine the largest possible moment due...

A 50-mm-diameter steel tube with a wall thickness of 2 mm just fits in a rigid hole. Find the tangential stress if an axial compressive load of 10 kN is applied. Assume υ = 0.30 and E = 200 X 10 N/m . Neglect the possibility of buckling.

NE Steel tubes (k =35 W/m2.K) of 400-mm inner diameter and 30-mm wall thickness are used to route superheated steam from the boller to the turbine in a power plant. Safety and economic concerns make it practical to add a 200-mm layer of Insulation (k =0.1 W/mK) to each tube, which is wrapped in a thin sheet of aluminum with an emissivity e =0.15. The air (with a convective coefficient h =5 W/m2K) and wail temperatures of the plant are...
