An antenna is guyed by three cables as shown. Knowing that the tension in cable AD is 270 lb, replace the force exerted at A by cable AD with an equivalent force-couple system at the center O of the base of the antenna.

ENGR 121: Computation Lab 1 Course Description Introduces computation and programming through the use of a mathematical computation system, such as MATLAB. Programming techniques and algorithmic problem solving are introduced in the context of data analytics, basic calculus, modeling, simulation, and visualization. The course also illustrates the strengths and limitations of the scientific software in solving mathematical, engineering and scientific problems. WEEK 1 Lecture 1 Summary of Lecture: beginning to understand the vocabulary and functions in MATLAB and how we will use MATLAB and BlackBoard Learn to turn in assignments, take quizzes, etc. Goal of the course: learn to THINK like a programmer aka step by step pr
