Consists of two gears A and B that are rotating about their mass centers. For gear A, mA = 3.8 kg and rA = 0.17 m. For gear B, mB = 9 kg and rB = 0.46 m. The radius of gyration for gear A is kA = 0.11 m and for gear B it is kB = 0.32 m. A clockwise couple Mo of magnitude 0.77 Mm acts on Gear A to start the system. The gears do not slip. (a) Draw the FBD and MAD for each gear and show all forces and resulting motions, (b) Determine the angular acceleration of each gear and the tangential contact force between the gears at C. Neglect friction.

answer: decibel

explanation:

double the distance = divide strength by 4

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
