Massless Strings and Frictionless Pulleys
Massless strings and frictionless pulleys? Whoever heard of such things? I attended Drexel University. Well, at first it was the Drexel Institute of Technology. I majored in chemistry. It was strongly suggested I major in chemical engineering. But I refused to change. Why? Because I didn't care what use humans put chemistry to. I loved chemistry and that was all there was to it. Unfortunately (or so it seemed at the time) majoring in chemistry didn't mean all my courses would be chemistry courses. Physics - Massless Strings & Frictionless Pulleys Well—unavoidably—I was required to take a certain amount of physics. And introductory physics requires the use of simple mathematics, including calculus. But physics equations can be difficult to derive. Simplification wherever possible was the mandate. This simplification required us…
