Figure 1 of 1 4 ft k= 50 lb/ft 2 ft -0 2 ft 4 ft Part A If each of the three links of the mechanism has a weight of 15 lb, determine the angle for equilibrium of the sprin which, due to the roller guide, always remains horizontal and is unstretched when 0 = 0°. (Figure 1) Express your answer using three significant figures. If there is more than one answer, enter them in ascending order separated by commas. 0 = [5] ΑΣΦ | | vec ? O
