The Question. A n₁-L P W इ B C n₂-L n₁.L D (n₁+n₂+n₁) L The figure (not drawn to scale) shows a overhanging metallic bar (supported at A and C), of flexural modulus EI. It is subjected to a point load of amplitude P at B, and UDL load w between points C and D. All distances are multiple of a unit distance L. You are given the distance between A and B as 4 x L, the distance between B and C as 3 x L, and the distance between C and D as 3 x L. (The length of the beam is thus 10 × L.) All answers can be expressed in term of fractions timed by functions of P, w, L and EI. a) Calculate the reaction forces at points A and C, RA and Rc. The answers are to be entered as fractions in the appropriate boxes below. RA ===== Rc= XP+ XP+ b) Calculate the bending moment at point C Mo. xwL (2 marks) xwL (2 marks) and the distance between C and D as 3 × L. (The length of the beam is thus 10 x L.) All answers can be expressed in term of fractions timed by functions of P, w, L and EI. a) Calculate the reaction forces at points A and C, RA and Rc. The answers are to be entered as fractions in the appropriate boxes below. RA = Ro= xP+ XP+ xwL (2 marks) xwL (2 marks) b) Calculate the bending moment at point C Mc.
