MAE 211: Engineering Mechanics 1. A 350-N force acts on a brake pedal, as shown in (a) If the pedal is in equilibrium in the position shown, what is the tension in the spring? (b) If the total de to 5 mm when the 350-N pedal force is at A is to be limited applied, what is the minimum required spring stiffness k? c) What are the pin reactions at D? First, draw the FBDI! 100 mm 50 mm 40 mm 350 N 30 mm 20° 20 mm
