Identify the conditions under which a given system of forces can be reduced to a single force (Check all that apply) O One can replace the force -couple system at O by a single force R acting along a new line of action if R and M, are mutually tangential. One can replace the force -couple system at O by a single force R acting along a new line of action if R and M, are mutually perpendicular. O One can replace the force -couple system at O by a single force R acting along a new →R line of action if R and M, are mutually parallel.
The combined action of the three forces on the base at O may be obtained by establishing their resultant through O. Determine the magnitudes of R and the accompanying couple M. Assume F₁ = 350 lb, F₂= 620 lb, F3 = 520 lb, a = 5.4ft, b = 2.9 ft. c = 4.0 ft, and 0 = 50% Answers: R= i 1091.134 lb M= i 9719.344 lb-ft
Knowing that = 36° and Mc = 350 ft-lb, reduce the force-couple system shown to an equivalent force and couple at point B. Enter the magnitude of the couple at B below in ft-lb to the nearest whole ft-lb. Enter a positive number if the couple at B is CCW and a negative number if the couple at B is CW. 4 Mc 50 lb 150 lb -3 ft- A 2 ft 4 ft
