Clutches, Brakes, Couplings, and Flywheels

The clutch is described as a machine element used to connect or disconnect two shafts together to transmit torque or power. The clutch works on the principles of friction. The clutch is commonly used in automobiles to transfer power from the driving shaft to the driven shaft.

Question

Need only a handwritten solution only (not a typed one).

Car A and Car B are initially traveling at 55 ft/sec. Car B applies
the brakes and slows down at a rate of 9.5 ft/sec^2. Car A
applies the brakes 0.24 seconds later which slows the car down
at a rate of A ft/sec^2? Find the minimum acceleration of car A to
stop before hitting car B if the starting distance is 9.0.
Given:
Starting velocity of both cars = 55 ft/sec
Starting distance between cars = 9.0
Car A starts slowing down 0.24 seconds after B does
Car B slows down at 9.5 ft/sec^2
Include graph showing position of each car as a function of time

Q3. The cable is pulled at Point P with a speed of vp = 0.1t² m/s as shown, where is in seconds. The Block B moves with a constant speed of 0.5 m/s. Determine the relative velocity and the relative acceleration of the Block A with respect to the Block B at t = 2 seconds. (Show your results as Cartesian vectors.) Note: If you do not know how you could solve for the velocity and the acceleration of the Block A, assume it is moving up at 2 m/s with an acceleration of 1 m/s² at t = 2 seconds in your analysis of the relative motion.

When the effect of aerodynamic drag is included, the y-acceleration of a baseball moving vertically upward is au = -g - kv², while the acceleration when the ball is moving downward is ad = -g + kv², where k is a positive constant and v is the speed in feet per second. If the ball is thrown upward at 94 ft/sec from essentially ground level, compute its maximum height h and its speed vf (a positive number) upon impact with the ground. Take k to be 0.0017 ft¹ and assume that g is constant. au=-g-ku² y 1 194 ft/sec Answers: h = Vf= i i ad=-g+kv2 h ft ft/sec
