4.Natasha has been told that if she reduces the thermostat setting on the heating system at her home by 1 degree, she will be able to reduce her present annual energy consumption of 5,000 kWh by 20%. In doing so, she will be able to save as much as $250 per year. a. What is the implicit cost of 1 kWh of energy consumption?If Natasha reduces the thermostat setting by another degree, she can reduce her annual energy consumption by another 10%. Based on your answer in Part (a), how much more money would she be able to save?​

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
