A pump is supported with four bolts as shown in Figure 1. All bolts (M10x1.5, SAE grade 1) are located 20 mm from each edge. There is an unbalance mass of m= 100 gr which is located at a distance of e= 150 mm from the centroid of the pump. Pump support (thickness of 10 mm) is made of cast steel (yield strength = 276 MPa, bearing strength = 300 MPa, ultimate strength = 414 MPa), meanwhile the steel foundation (width x length x thickness: 200 x 200 x 12 mm) is made of mild steel with yield strength of 250 MPa. Assume the unbalance mass is located at the middle of bolt connection. For known condition: (a) Draw the free body diagram when the unbalance mass positioned at y (+) direction (b) Determine the magnitude of centrifugal force due to the unbalance massif the rotation of motor is 1750 rpm. (c) What tightening torque should be used if the connection is permanent and the fasteners are lubricated? (d) Determine the factors of safety guarding against yielding, overload, and joint separation 120 mm 11 160 mm 120 mm 4 Bolts tutu 200 Pump support Steel Foundation 80 mm (C) Top view (b) Front view
