The problem involves a traffic-light assembly with vertical and horizontal poles. The task is to determine the additional force and moment reactions at the base, labeled as point O, caused by the addition of three 114-lb traffic signals positioned at points B, C, and D. The results are to be reported as a force magnitude and a moment magnitude.Diagram Explanation:- The diagram shows a vertical pole with an arm extending horizontally, supporting three traffic signals.- Signals B and D are located on either end of the horizontal arm, each weighing 114 lb. Signal C is in the middle.- The distances from point A (the vertical pole) to each signal are given: 27 feet to B and C, and 35 feet to D.- The coordinate axes labeled x, y, and z help in visualizing the spatial arrangement.Solutions:- Force at base O: 352 lb- Moment at base O (\(M_O\)): 10,059.17 lb-ftThese calculations consider the combined effects of the weights of the traffic signals and their distances from the base.

Given that → wt. of lights →114 lb each

The specialty wrench shown in the figure is designed for access to the hold-down bolt on certain automobile distributors. For the configuration shown, where the wrench lies in a vertical plane and a horizontal 290-N force F is applied at A perpendicular to the handle, calculate the moment Mo applied to the bolt at O. For what value of the distance d would the z-component of Mo be zero? Assume a = 85 mm, d = 155 mm, h = 150 mm, 0 = 28° F Answers Mo = ( i d = i 0 h i+ i mm j+ i k) N.m
