The T-shaped structure is embedded in a concrete wall at A and subjected to the force and the force-couple system 1550 N and 1,850 N-m at the locations shown. Neglect the weight of the structure in your calculations for this problem. a.) Compute the allowable range of magnitudes for in the direction shown if the connection at will fail when subjected to a resultant moment with a magnitude of 880 N- m or higher. b.) Focusing on the forces and igonoring given for now. Using the value for F1,min that you calculated in (a), replace the two forces F₁ and F₂ with a single force that has equivalent effect on the structure. Specify the equivalent force Fein Cartesian components and indicate the horizontal distance from point A to its line of action (note this line of action may not intersect the structure). c.) Now, model the entire force system (F1,min, F2, and M) as a single force and couple acting at the junction of the horizontal and vertical sections of the structure. Enter your answers in Cartesian components. Variable Value a b A С 0 -b Values for dimensions on the figure are given in the following table.
