Design a small, single-cylinder, piston-type steam engine and boiler that can be used to power a toy vehicle, such as a train or a tractor.
Choose a convenient fuel such as alcohol, and design the boiler so that it can supply enough steam to your engine. Make sure the boiler has a pressure relief valve, and pay close attention to other safety considerations.
A driver applies a horizontal force of 20 N (to the right) to the top of a steering wheel. Calculate the angular acceleration of the steering wheel about the central axis
An object is placed 10 cm in front of a concave mirror whose focal length is 17 cm. The object is 3.02 cm tall. Using a ray diagram drawn to scale, gauge the location and the height of the image. The mirror should be drawn to scale.
When a 19.7 kg wheel with an angular speed of 2.30 rad/s is disconnected from a motor, a 0.219 N · m frictional torque slows the wheel to a stop. how long will it take for the wheel to come to rest
The rotor (flywheel) of a toy gyroscope has mass 0.150 kg . Its moment of inertia about its axis is 1.20×10-4kg·m2. The mass of the frame is 2.70×10-2 kg .
An airplane releases a ball as it flies parallel to the ground at a height of 145 m as shown in the figure. If the ball lands on the ground exactly 145 m from the release point, calculate the speed v of the plane. Neglect any effects due to air resis..
Vector A has a magnitude of 8 units and makes an angle of 45.0° with the positive x-axis. Vector B also has a magnitude of 8.00 units and is directed along the negative x-axis. (Using graphical methods), find (a) vector sum A + B and (b) vector diffe..
