A metal die, shaped like a hockey puck, is 80 mm in diameter and 50-mm thick. The thermal conductivity of the die is 12.5 W/m.°C, density is 1800 kg/m³, and specific heat is 600 J/kg. °C. In the process of making it, the die is initially heated up to 240°C, and then slowly cooled to 40°C by dropping it in cold bath at 10°C. The average convection coefficient in the bath around the die can be assumed to be 30 W/m².°C. (a) Find the Biot number to verify lumped capacitance applicability. (b) How long will the cooling process take? 81485 0¹027

A of the velocity in m/s of point B. - OB

Please answer 3, 4, 5, 6, 8, 9, 10, 12 1 is 0, 2 is 0, 7 is point A, 11 is 2.  I included a picture of someone who solved but they were mostly incorrect. Please do not answer if the solution set I provided with the incorrect answers was you. I appreciate the attempt, but the solutions for 3, 4, 5, 6, 8, 9, 10, 12 were marked wrong, so unless you have different answers, please do not submit the same incorrect solution set. The wheel is attached to the spring. The mass of the wheel is m=20 kg. The radius of the wheel is 0.6m. The radius of gyration kG=0.4 m. The spring’s unstretched length is L0=1.0 m. The stiffness coefficient of the spring is k=2.0 N/m. The wheel is released from rest at the state 1 when the angle between the spring and the vertical direction is θ=30°. The wheel rolls without slipping and passes the position at the state 2 when the angle is θ=0°. The spring’s length at the state 2 is L2=4 m. (1) If the mass center G is set as the origin (datum), the gravitational…

i) The displacement at point A. Enter your answer in mm to 2 decimal places.

A hole is to be drilled as shown by the circle. Using the part geometry shown below, indicate on the part sketch where locator(s) should be positioned according to the 3-2-1 principle. Use dashed lines to indicate locators on hidden surfaces. Also indicate where clamping force(s) should be applied using arrows. Use the minimum number of clamping forces.
