Transcribed Image Text:Stiffness equation: W A; E; %3D Bucket R 13, A3´ -Telescoping arm 2, A2 4, A1 45° Figure Q1 ---- -----.
(a) Figure Q1(a) shows a fire truck system which consist of a bucket attached at the end of the telescoping arm. Given that the mass of the bucket including the fireman is W = Q kg, the length of the telescoping arm given as l1 = l2 = l3 = R m, with cross- sectional areas of A1 = S cm?, A2 = T cm? and A3 = U cm? and Young's modulus, E = 2.5 x 10' Pa. Q1 Note: The values of Q, R, S, T and U depend on the respective 2nd, 3rd, 4th, 5th, and 6th digits of your matric number number is AD170154 gives the value of Q = 650 kg, R = 10 m, S = 40 cm², T = 10 cm? and U = 4 cm?. shown in Table Q1. For example, if your matric (i) Analyze the total stiffness of the telescoping arm in a vertical direction. (ii) Determine the natural frequency of the system.
