Extracted text: (b) Figure Q3(b) shows a uniform bar AB of mass = 8 kg hinged at point C. Point A is connected to a spring to maintain the bar in vertical direction, and the stiffness k = 500 N/m. If point A is displaced counter-clockwise by a small angle 0 = 3.5 degree and released, (i) With the free body diagram and kinetic diagram, determine the initial horizontal displacement of A. (ii) Determine the period of vibration. (iii) Determine the maximum velocity and acceleration at point A. mive 950 mm G 40 mm В Figure Q3(b)
