A square hole is to be cut using ECM through a plate of low alloy steel that is 12 mm thick. The hole is 35 mm on each side, but
the electrode used to cut the hole is slightly less than 35 mm on its sides to allow for overcut, and its shape includes a hole in its center to permit the flow of electrolyte and to reduce the area of the cut. This will produce a center core that can be removed after the tool breaks through. This tool design results in a frontal area of 245 mm2 . The applied current = 1200 amps.
Using an efficiency of 95%, how long will it take to cut the hole?

Answer:
Time to machine is 348.5secs
Explanation:
The ECM means Engine Control Module (ECM) it can also be called the Engine Control Unit (ECU), it makes sure that your vehicle operates at optimal performance. The ECM also monitors most of the sensors in the engine bay in thereby managing your vehicle’s air-fuel mixture and regulate the emission control systems.

Answer:
E = 2940 J
Explanation:
It is given that,
Mass, m = 12 kg
Position at which the object is placed, h = 25 m
We need to find the potential energy of the mass. It is given by the formula as follows :
E = mgh
g is acceleration due to gravity
So, the potential energy of the mass is 2940 J.
