Extracted text: Problem 5: A beam is 250 mm in width, 500 mm in total height and 3.5 meters in length. This beam was tested under 4-points loading, and the shear span (a) was 1.2 mcters (this is the distance between the applied load and the support). Tests on the same concrete used in this beam were conducted on cylinders and the compressive strength was measured to be 32 MPa. a- Calculate the flexural Modulus of Rupture (f) as recommended by ACI code b- Calculate the bending (i.e. flexural) moment at which flexural cracking is expected C- Calculate the maximum total load which can be carried by the beam.
