Afreighter is moving at a speed of 8 knots when its engines suddenly stop. if it takes 10 minutes for the freighter's speed to reduce to 4 knots, determine its speed and distance travelled 30 minutes after the engines were stopped. the freighter's deceleration is proportional to the square of its speed, i. e., a = -k*v^2. (1 knot = 6076 ft/hr)

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges
