- The car having a weight of 3200 lb travels up the incline at a constant speed of 60 mph. Determine the output power required of the the motor. Express the answer in horsepower. Ignore drag and frictional forces. note: 1 hp = 550 ft- lb/sec.arrow_forwardQ8) You are designing a system for moving aluminum cylinders from the ground to a loading dock. You use a sturdy wooden ramp that is 2.00 m long and inclined at 37.0 degrees above the horizontal. Each cylinder is fitted with a light, frictionless yoke through its center, and a light (but strong) rope is attached to the yoke. Each cylinder is uniform and has mass 420 kg and radius 0.300 m. The cylinders are pulled up the ramp by applying a constant force F to the free end of the rope. F* is parallel to the surface of the ramp and exerts no torque on the cylinder. The coefficient of static friction between the ramp surface and the cylinder is 0.120. a) What is the largest magnitude F° can have so that the cylinder still rolls without slipping as it moves up the ramp? b) If the cylinder starts from rest at the bottom of the ramp and rolls without slipping as it moves up the ramp, what is the shortest time it can take the cylinder to reach the top of the ramp?arrow_forwardThe W1= 54.98-lb block shown rests on a smooth plane (coefficient of kinetic friction = 0) with an angle of 0-29° from horizontal. It is connected by á flexible inextensible cord that passes around weightless, frictionless pulleys to a support. The W2 =113.71-lb weight is attached as shown. After the system is released from rest, in what distance will the block on the plain attain a speed of 9.4 ft/s? %3D W2 W1arrow_forward
- Buoyancy 4Q. A balloon uses hot air to provide its lifting capability. Prior to its release it is tethered to the ground by a steel cable. If the gondola, weights, passengers, and material weigh 2000 lb, determine the tension in the cable when the balloon is inflated as a sphere having a diameter of 60 ft.

None of the above « Question 15 of 50 Moving to another question will save this response.arrow_forwardIn indoor plumbing, water must often be redirected and split when a pipe approaches a wall. Consider a situation like this in which the pipes are all horizontally oriented. Water is flowing at a velocity of 13 feet per second in a pipe of 9-in diameter at 28 psi before it is split in the tee pictured here into two pipes of 2-in diameter. Assume that the exiting flowrate in each of the branches of the tee are equal. What is the force in pounds of the water on the tee? Though the tee appears to be vertically oriented in the drawing so that you can see how the water is flowing, the tee is horizontally oriented.arrow_forward
