One plate (with k=15W/m-K, p=6500kg/m3, cp=450J/kg-K, thickness of 0.2m, and initial temp of 465K) is pushed against another plate (with k=10W/m-K, p=4000kg/m3, cp=525J/kg-K, thickness of 0.2m, and initial temp of 375K) both having their opposite sides insulated. After a total of 115 seconds passes (since the plates touch), what is the temperature of the hotter plate's exposed surface?

A 600 mm diameter pulley is mounted at a distance of 300 mm to the right of left hand bearing and this drives a pulley directly below it with the help of belt having maximum tension of 2.25kN. Another pulley 400 mm diameter is placed 200 mm to the left of right hand bearing and is driven with the help of electric motor and belt having maximum tension of 3.376kN, which is placed horizontally to the right. The angle of contact for both the pulleys is180° and =0.24.
