The spring of modulus k = 870 N/m is stretched a distance ō = 71 mm when the mechanism is in the position shown. (a) Calculate the force Pmin required to initiate rotation about the hinge axis BC, and determine the corresponding magnitudes of t bearing forces which are perpendicular to BC. (b) What is the normal reaction force at Dif P = Pmin/2? 95 mm 55 mm C 146 mm k = 870 N/m 49 mm 173 mm B 49 mm 55 mm 129 mm 46 mm

If you were manufacturing a precision component which has a mass of around 15 grams and which was a solid 3D shape, which method would be appropriate?
