Qu 4 The 12-kg slender rod is attached to a spring, which has an unstretched length of 2 m. If the rod is released from rest when 0 = 30°, determine its angular velocity at the instant 0 = 90°. 2 m B k = 40 N/m 2 m
CORRECT AND DETAILED HANDWRITTEN SOLUTION WITH FBD ONLY. I WILL UPVOTE THANK YOU. CORRECT ANSWER IS ALREADY PROVIDED. 13: A cantilever beam is of length 1.5 m,loaded by a concentrated load P at its tip as shown inFig. 8-18(a), and is of circular cross section (R = 100 mm),having two symmetrically placed longitudinal holes asindicated. The material is titanium alloy, having anallowable working stress in bending of 600 MPa.Determine the maximum allowable value of the verticalforce P. ANS: P = 236,589.076 N = 236.589 kN
CORRECT AND DETAILED HANDWRITTEN SOLUTION WITH FBD ONLY. I WILL UPVOTE THANK YOU. CORRECT ANSWER IS ALREADY PROVIDED.  15: Consider a beam having an I-type cross section as shown in Fig. 8-45. Ashearing force V of 150 kN acts over the section. Determine the maximum and minimumvalues of the shearing stress in the vertical web of the section.ANS: fv(max) = 44.048 MPa ; fv(min) = 33.202 MPa
