MECE2420 Solid Mechanics Q1. The beam AB is fixed to the wall and has a uniform weight of 1200 N/m. If the trolley supports a load of 6000 N, determine the resultant internal loadings acting on the cross sections through points C and D. 1.5m - 6 m Q2. The shaft is supported by a smooth thrust bearing at A and a smooth journal bearing at B. Determine the resultant internal loadings acting on the cross section at C. 600 N/m Q3. Determine the resultant internal loadings acting on the cross section through point C. Assume the reactions at the supports A and B are vertical. Q4. The force applied at the handle of the rigid lever causes the lever to rotate clockwise about the pin B through an angle of 2. Determine the average normal strain developed in each wire. The wires are unstretched when the lever is in the horizontal position. 100 kN/m Assignment #1 6000 N 3 m -1m B +1 ml ml m-1.5 m-1.5 n C D 1m 2 m 200 mm 900 N 100 kN/m 200 mm 200 mm 300 mm 300 mm F B
