How to solve a motor with a gearbox inside provides torque onto a shaft connecting to a $24$ tooth gear, which the $24$ tooth gear connects to a $36$ tooth gear and back to a $24$ tooth gear. A lead screw with apme threads is connected to the gear via a shaft. A block is attached to the apne rod with a threaded brass bushing inside. As the motor turns the lead screw the block remains fixed and does not rotate or move in the x or z direction only moving in the y direction $($up or down$).$ A$)$ calculate the torque applied onto the block? B$)$ calculate the moment force on the block? C$)$ Calculate the force exerted onto the block by the motor? D$)$ if the block had a mass of $100$ lb can the motor lift it up$?$ A diagram and the spectre of the motor, motor gear box and gears are provided.
