Homework Statement
I am currently tring to work out the torque that is required to lift a bike seat of mass 2kg at a rate of 10mms-1 with a given screw thread and nut. how would i go about this?
Also is it possible to calaculate the shear force experienced by the thread of the screw and nut when a body of mass 100 kg is sitting on the seat, with the full downward force being applied through the thread?
Attached is an image of the cross section of the design in a CAD suite.
Homework Equations
i understand that torque = Radius * Force
The Attempt at a Solution
torque = Radius of the shaft (14mm) * force of gravity acting on the seat (20N)
