The beam is made of elastic perfectly plastic material. Determine the shape factor for the cross section of the beam (Figure Q3). [Take σy = 250 MPa, yNA = 110.94 mm, I = 78.08 x 106 mm²] y 25 mm 75 mm I 25 mm 200 mm 25 mm 125 Figure Q3

I keep trying to figure this out but every time I calculate it I keep getting numbers that don't make sense, can you please help me out with this?

Consider the beam in the picture below: 7kN/m 5kN/m P N/m Section 1 Section 2 Section 3 - L/3 L/3 L/3 Take P = the last four digits of your student number in N/m. If P<250 N/m then take P = 30OON/m instead. Take L = the third digit of your student number, reading left to reight. If this value is zero then take L = 2 Assume: The reaction at the Pin = Vnin 47000L+9PL )N %3D 54 The reaction at the Roller = Vroller = 61000L+9PL 54 N and that both reactions act vertically upwards. a) Find an expression for the internal moment for Section 1. Show all working and any relevant free body diagrams. b) What is the maximum magnitude of the internal moment for Section 1? Mark sure you prove that the value you calculate is the maximum. c) Find an expression for the internal moment for Section 2. Show all working and any relevant free body diagrams. d) What is the maximum magnitude of the internal moment for Section 2? Mark sure you prove that the value you calculate is the maximum. e) Find an…

A steel beam with length 4 m is to be connected between two columns (Column A and Column B) as shown in Figure 1. This beam is found to be short by 2 mm. Determine the force needed to pull the beam so that it can be connected at the two columns. The cross-section of the beam is shown in Figure 2. Column A Column B L= 4 m 50 mm a uniform thickness 5 Веат mm 100 mm 2 mm Ebeam = 210 kN/mm? Section a-a 2 m 3 m Figure 1 Figure 2
