5. Below Fig. shows the mechanism of a quick return motion of the crank and slotted lever type shaping machine. The dimensions of the various links are as follows: OA = 200 mm; AB = 100 mm; OC = 400 mm; and CR = 150 mm. The driving crank AB makes 120° with the vertical and rotates at 60 r.p.m. in the clockwise direction. Find: 1. velocity of ram R, and 2. angular velocity of the slotted link OC. (0.8 m/s; 1.83 rad/s) R

Calculate the rate of flow of waste thermal energy out of the engine in the exhaust gases in kW (to 1 decimal point). If the air inlet temperature is 35 °C, the air to fuel ratio is 10:1, the inlet air mass flow rate is 37 kg/hr, the specific heat capacity of exhaust gas is 1.13 kJ/kg/K, and the exhaust temperature is 500 °C. Add your answer Integer, decimal or E notation allowed

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).  It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).

can you provide an answer easie to read. the answer is put into sentences like fcv=mgcos 6
