Question

QUESTION 2 The bent rod OABDE shown in Figure 02 is supported by a ball and socket joint at 0, a radial bearing at D, and cable AF. The rod is subjected to a 200 N load applied at B. The mass of the bent rod can be neglected. The radial bearing E does not support any axial force and moments. For this instant: - a) Draw the free body diagram of the bent rod OABDE. b) Determine the reactions at O and E. c) Find the tension in cable AF. 10 marks SOALAN 2 Rod bengkok OABDE seperti dalam Rajah S2 disokong oleh bebola dan soket di O, gelas jejarian di D dan kabel AF. Rod ini dikenakan beban 200 N di B. Jisim rod boleh diabaikan. Galas jejarian E tidak menanggung sebarang daya paksi mahupun momen. Pada ketika ini:- a) Lukis gambarajah badan bebas bagi rod bengkok OABDE. b) Tentukan tindakbalas di O dan E. c) Dapatkan ketegangan kabel AF. 10 markah 0.7 m 0.4 m 0.4 m 0.3 m 0.2 m B 0.2 m 0.2 m P = 200 N .
