The rigid beam ABC is supported by a pin connection at C and by steel rod (1), which has a diameter of 7 mm. If the normal stress in rod (1) must not exceed 215 MPa, what is the maximum uniformly distributed load w that may be applied to beam ABC? What is the allowable force in road (1)? Use dimensions of a = 350 mm, b = 700 mm, and c = 525.0 mm.
A rigid beam ABC is supported at C by a pin support, and at A and B by timber struts AD and BE which are in turn supported by pin supports at D and E respectively (Figure 1). The struts AD and BE are constructed using F11 timber (refer Figure 2) with square cross section 40 mm x 40 mm. A uniformly distributed load of 10 kN/m acting horizontally to the right is applied along the complete length ABC. Under the action of this load, in addition to any changes in the lengths of the struts, the pin support at C settles by 1 mm to the right. Assume that the beam and struts are weightless and that the struts will not buckle. (a) Using equilibrium and compatibility considerations determine the support reactions at C, D and E. Hint: Since the struts AD and BE can transfer only axial force, the reactions at D and E act horizontally (that is, there are no vertical reaction components at D and E). (b) Find the normal stress, normal strain and change in length of strut AD.
