The brake pedal ABCD for an automobile has a torsional spring at pin C. The spring has 4000 N-mm/rad stiffness and isprewound by 1/2 of a turn so that contact is made at point E when P= Q = 0. The pedal has negligible weight. Take thevalue of Pto be 80 N.NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.200-1801D10°160dimensionsin mm90Determine the value of Q that will cause the pedal to begin to move and the reactions at C.
