    Solving Shear Stress on a Bar - Mechanics of Materials

    I'm trying to understand a problem found on Mechanics of Materials and did not completely understood the problem. I can solve problems like this but I still don't know why I'm solving this way. It is a simple question: Why the shearing force V does not cause shear stress (\tau_2) on the point A...

    Graduate Differential equation for projectile

    Using your example I was able to see how to reach the first example (only gravity) and found the quadratic equation as solution However I had no time to test the second example (gravity+wind) in fact I did not get the general idea, maybe I'm not seeing something but here is what I've found...

    Graduate Differential equation for projectile

    I want to model a Differential Equation for a projectile motion under 2 forces (gravity and wind) So, what I have now is an algorithm that simulate the parametric motion (2d) of the project under those 2 forces (given a P position of the projectile with velocity V under a vector of forces F (or...

    Automotive Calculating Car Braking Distance: Reliability & Factors

    I always found this an interesting question How can you measure the braking distance of a car with a good reliability in normal conditions? From classical physics, we can assume that the braking distance can be found by determining the work needed to dissipate the vehicle kinetic energy...
