The spanner shown is used to rotate a shaft. A pin fits in a hole at A, while a flat, frictionless surface rests against the shaft at B. If a 60-lb force P is exerted on the spanner at D, find the reactions at A and B.
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
