Bending Moment and shear force diagram for overhanging beam Problem 5-4 Determine the values and draw the diagrams for shear force (/mech/sf.htm) and bending moment (/mech/bm.htm) due to the imposed load on overhanging beam shown in figure 5-4(a) and find the position of point of contra- flexure, if any. 20 kN 10 kN/m A. 7B C -2m| 4m Figure 5-4(a) Solution: The overhanging beam is a beam which has unsupported length on one or both sides. Calculation of support reactions

Q4

Learning Goal: To understand how to use the relative position and velocity equations to find the linear and angular velocity of members in an assembly. A piston is driven by a crankshaft as shown. The crank arm (member AB) has a length of r₁=0.55 in and the connecting rod (member BC) has a length of r2 = 4.25 in. The crankshaft rotates in the counterclockwise or positive direction. (Figure 1) Figure C 1₂ @₂ @1 0 B X 1 of 2 Part C - Velocity of C Find the magnitude of the velocity of C, vc, when the piston has moved to the new position = 33.0° and p = 6.23°. The crankshaft (member AB) is still rotating at 300 rpm Express your answer to three significant figures and include the appropriate units. ► View Available Hint(s) vc= 15.5 in S Submit Completed Part D - Rotational Speed of the Crankshaft W1 = Previous Answers The velocity of the piston is vc = 70.0 in/s j the instant when 0 = 33.0° and = 6.23°. Find the rotational speed of the crankshaft (member AB) at this instant. The crankshaft…

Can you please solve for va and vb. This is not what I asked for

I have been working on this Solid Mech problem for a while and have gottem nowhere we are supposed to be finding the modulus of elasticity for a set of data (attached). I have made an excel sheet from this to finda stress strain graph. I understand how the modulus of elasticity is (E = (delta stress)/(delta strain)) but I cannot find the propotional limit that I need to find delta stress and delta strain
