Required information The I beam shown is statically indeterminate. Under certain circumstances, it may be appropriate to nts use a model where the I beam is rigid and the roller supports at points B and Care replaced by vertical springs of equal stiffness so that the support reactions may be determined. Take the value of Pto be 800 lb. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this eBook part. Hint PA B 2 ft - 2 ft Print References Determine the reactions at points A, B, and C using this approach. (Do not include a minus sign in your response.) The horizontal component of the reaction force at A is 0 lb -+. The vertical component of the reaction force at A is lb 1 The vertical component of the reaction force at B is Ib 1 . The vertical component of the reaction force at C is Ib T
