For operating the exhaust valve of a petrol engine, the maximum load required on the valve is 5000 N. The rocker arm oscillates around a pin whose centre line is 250 mm away from the valve axis. The two arms of the rocker are equal and make an included angle of 160°. Design the rocker arm with the fulcrum if the tensile stress is 70 MPa and the bearing pressure is 7 N/mm2 . Assume the cross-section of the rocker arm as rectangular.

Question
For operating the exhaust valve of a petrol engine, the maximum load required on
the valve is 5000 N. The rocker arm oscillates around a pin whose centre line is 250
mm away from the valve axis. The two arms of the rocker are equal and make an
included angle of 160°. Design the rocker arm with the fulcrum if the tensile stress is
70 MPa and the bearing pressure is 7 N/mm2
. Assume the cross-section of the rocker
arm as rectangular.
