A new winch (a cable driven by a motor) is to be used to hoist loads up an inclined ramp. Your supervisor is worried about the packages arriving too quickly at the top of the ramp. Constraints The inclined ramp is made up of small cylinders that are free to rotate: there is no friction between the ramp and the load.The angle theta of the ramp from the horizontal is known.The winch cable exerts a known force.The cable is oriented at an angle a from the horizontal.The charge, initially immobile, has a known mass.The length of the ramp is known. Schematization Draw a diagram of the object that interests us. Draw your x and y axes. Draw and name each force experienced by the object that interests us. Modelization Build a model to calculate the final speed of the load as it arrives at the top of the ramp, given the known parameters. Then test your model with the following values: Ramp…arrow_forward
- Red blood cells can be separated from blood plasma using a centrifuge. This device spins the whole blood samples rapidly in a circular path and can generate forces many times that of gravity. The more dense material (red blood cells) accumulates at the outer end of the container while the less dense material (plasma) is closer to the centre of rotation. One “g” is the equivalent of 9.80 ms-2. How many “g”s is experienced by the material spinning in the centrifuge at a distance of 18.4 cm from the centre of rotation at 2,457 revolutions per minute?arrow_forwardA highway curve has a radius of 0.14 km and is unbanked.

- A small ball is attached to one end of light rope that has a length of 4.0 m. The other end of the rope is attached to the ceiling. The ball is held with the rope horizontal and released from rest.

Once the station is completed, it is set rotating at a rate that requires an object at the rim to have radial acceleration g , thereby simulating Earth's surface gravity. This is accomplished using two small rockets, each with 130 N thrust, that are mounted on the rim of the station. How long will it take to reach the desired spin rate, and how many revolutions will the station make in this time?arrow_forward
