Q3. Consider the frame shown in the figure below. The steel bar AB is pin connected at its ends and has a rectangular cross section. Est = 200 GPa, σY = 360 MPa. Suppose that L = 5.5 m and l = 2.5 m.
Determine the maximum allowable intensity w of the distributed load that can be applied to BC without causing AB to buckle. Use a factor of safety with respect to buckling of 1.5.
Express your answer to three significant figures and include the appropriate units.
Answer:
Q4. The copper pipe has an outer diameter of 42 mm and an inner diameter of 37 mm. It is tightly secured to the wall at A and three torques are applied to it as shown in the figure below.
Determine the absolute maximum shear stress developed in the pipe.
Express your answer to three significant figures and include the appropriate units.
Answer:
Q5: A hollow cylindrical steel shaft is 4 m long and has inner and outer diameters equal to 50 mm and 70 mm, respectively. It is fixed at end A as shown in Figure 3.
