Challenge Problems
Push your limits with advanced challenges
Given a slider-crank mechanism where the crank radius is 0.15 m and the angular velocity is 10 rad/s, calculate the piston acceleration at a crank angle of 30 degrees. Assume the connecting rod length is 0.5 m.
💡 Hint: Make sure to convert angle measures where necessary and use values in their proper units.
Calculate the net driving torque required for a given mechanism if the effective force on the connecting rod is 50 N and the distance from the crank pivot to the slider pin is 0.2 m.
💡 Hint: Remember that torque is a product of force and radius!
