(MB), (MB) = -420,-700,0 lb-ft Previous Answers All attempts used; correct answer displayed Here we learn how to determine reaction moment by using equilibrium equations and accounting for a constraint laid upon the system by the support. The bar AB is supported by two smooth collars as shown in (Figure 1). At A the connection is with a ball-and-socket joint and at B it is a rigid attachment. Suppose that F= 70 lb load is applied to the bar. Figure 6ft E X 3 ft. B < 1 of 1 > A 5ft F y 6 ft Part A Determine the x, y, z components of reaction force at A using scalar notation.
