The ball shooting mechanism from a pinball machine is shown. Name The motor provides the torque...
A motor provides the torque necessary to keep a gear turning at
constant angular velocity, overcoming friction between the gear and
the axle.
The gear can be modeled as a disk, with mass 2 kg, and radius
rg = 0.2 m. The force of friction can be
modeled as a single force, acting at the outer edge of the axle, at
position ra = 0.02 meters, with force of
fk = 10 N.

Consider the DC motor-driven wheeled mobile robot shown in figure, in which m is the mass of the wheeled mobile robot, r is the radius of the driving wheel, and T is the torque delivered to the wheeled mobile robot by the DC motor. For simplicity, the motion is restricted to one spatial dimension. The figure also shows the simplified drive system, including the equivalent electrical circuit of the DC motor, the gears, and the driving wheel. The motor parameter...
The assembly shown in the figure below consists of a thin rod of length l = 23.9 cm and mass m = 1.20 kg with a solid ball of diameter d = 10.0 cm and mass M = 2.00 kg attached to its top. The assembly is free to pivot about a frictionless axle through the bottom of the rod. The assembly is initially vertical and at rest when it starts to rotate clockwise. (a) After the combination rotates through 90...
2018 ENGD2005 De Montfort University 3. An electric motor M drives a flywheel F via the transmission schematically shown in Figure 3. Gears A and B have 30 and 200 teeth, gears C1 and C, have 100 and 25 teeth, and gears D, and Di have 96 and 40 teeth, respectively. The moments of inertia of the system components are following: the motor and gear A is 0.025 kgm, compound C (gears C, C and connecting rod) is 0.015 kgm2,...
1 m Mm F Sl. In the mechanism shown the circular body with the mass moment of inertia I about 0. i.e. the center of gravity of the body, rotates about O. The T shaped body with the mass m is attached to that circular k body through the joint A such that OA = r. and it translates along the horizontal direction. The linear spring with stiffness k is placed between the T shaped body and the ground such...

Winter Work Packet 2018 Th is packet is designed to help you study on kinematics and rotational motion during the break. It is requested that you complete this packet if you currently have less than a 65%, but all students are welcome to complete it. This packet will be due the first day of school, I will not accept it any later. I will be available to help with any questions regarding the problems via REMIND on Wednesday the second...

4/5 a the minimum kinetic energy at the apping point? (C) Use conservation of energy to determine the minimum angular velocity of the block just after the collision, (d) then use conservation of angular momentum during the collision to find the initial speed of the bullet vo. (Hint: Ignore the mass of the bullet after the collision. The moment of inertia of the cube about its bottom-right edge...
