SECTION A: MATERIAL
QUESTION 1
1) Here below is one of the beams of an overhead transportation system use in warehouse. The
displacement of objects is done through a bloc of trolleys as indicated in figure 6 below.
Considering that: F1 = 20kN and F2 = 30kN
a) Calculate the resultant force and indicate its position about C1 (4 marks)
b) Determine using Barre’s Theorem the maximum bending moment under each wheel or load and
indicate the critical position of the trolley (neglect the self-weight of the profile). (10 marks)
c) Position the wheel C1 on the beam such as to obtain the maximum shear force in the beam and
calculate its value. (6 marks)
