Question
1. If a force of magnitude F can be applied in four different 2-D configurations (P. imum and minimum torque Q. R, & S), select the cases resulting in the maxi values on the nut. (Max, Min). P. 2. A 50 N couple is applied to the beam as shown. Its moment equals Nm 50 N A) 50 C) 80 D) 100 3. You can determine the couple moment as M-F IF 20 k lb, then r is: A) rBc B) FAB C) rcs rBA 4. Which equation of equilibrium allows you to determine Fa right away? 100 ib MA-O D) Any one of them The smooth pipe which rests against the opening at the points of contact A, B, and C. In a FBD of only the pipe, there are how many unknowns? 5. Two forces and one couple moment Three forces and one couple moment 05 015m 300N C) Three forces D) Four forces 6. The pipe assembly shown is supported at A by a bearing and to the wall at Determine the type of constraint and determinacy of this rigid body A) Improper Constraint, Statically Determinate B) Redundant Constraint, Statically Determinate C) Improper Constraint, Statically Indeterminate D) Redundant Constraint, Statically IndeterminateExplanation / Answer
B) Redundant constraint , statically determinate
because external force balenced by support reaction and system also stable because no of road+ support reaction = 2* no of joints hence we say that system is determinete
