Program to calculate the average of a set of grades and count the number of failing test grades •Name your program lab4.c •Start by asking the user how many grades are to be entered.•Then ask for each one of theses grades. Calculate the average grade and the number of failing grades (grade less than 70)Display on the screen the average grade and the number of failing grades

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

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.
