Tenemos el eje de un motor que gira a 2.000 rpm con una polea A de 20 mm de diámetro acoplada a su eje. Si unimos mediante una correa la polea A con otra polea B que mide 80 mm de radio. ¿Se trata de un mecanismo reductor o multiplicador de velocidad? ¿Qué velocidad adquirirá el eje de la segunda polea B?

Requirement types discussed during software development include functional and color scheme nonfunctional and code style constraint and nonfunctional fashionable and functional.

Awell-diversified portfolio needs about 20-25 stocks from different categories.

The volume v and paper surface area a of a conical paper cup are given by where r is the radius of the base of the cone and h is the height of the cone. a. by eliminating h, obtain the expression for a as a function of r and v. b. create a user-de ned function that accepts r as the only argument and computes a for a given value of v. declare v to be global within the function. c. for v ! 10 in.3 , use the function with the fminbnd function to compute the value of r that minimizes the area a. what is the corresponding value of the height h? investigate the sensitivity of the solution by plotting v versus r. how much can r vary about its optimal value before the area increases 10 percent above its minimum value?
