44. A mediados de la década de 1960, la McGill University lanzó sensores metereológicos de gran altitud al dispararlos desde un

cañón hecho de dos cañones de la Armada de la Segunda Guerra Mundial, atornillados uno tras otro para tener una longitud total de 18 m. Se propuso que este arreglo se usara para lanzar un satélite. La rapidez orbital de un satélite es de unos 29 000 km/h. ¿Cuál tendría que ser la aceleración me- dia a lo largo de los 18 m del cañón, para tener una velocidad de 29 000 km/h a la salida de la boca del cañón para este sa- télite? ​

La cinemática permite encontrar la respuesta para la aceleracion del cuerpo en el cañón es:

            a = 1,8 10⁶ m/s²  

 

La cinemática estudia el movimiento de los cuerpos, buscando relaciones entre la posicion, la velocidad y la aceleración.

       v² = v₀² + 2 a x

Donde v y v₀ son la velocidad actual e inicial, respectivamente, a es la aceleracion y x la distancia recorrida.

Indica que la longitud de cañon es x= 18 m la velocidad de  salida es  

            v= 29000 km/h ( \frac{1000m}{1 km} ) ( \frac{1h}{3600s} s) = 8,055,56 m/s.

La velocidad inicial del proyectil es cero.

            a = \frac{v^2}{2x}  

            a = \frac{ 8055.56^2}{2 \ 18}  

            a = 1,8 10⁶ m/s²  

En conclusión usando la cinemática podemos encontrarla respuesta para la aceleracion del cuerpo en el cañón es:

            a = 1,8 10⁶ m/s²

A wheel is used to turn a valve stem on a water valve. How much is the mechanical advantage when an effort of 80 lbs. is applied
Ann [662]

Answer:

4

Explanation:

From the question given above, the following data were obtained:

Effort (E) = 80 lbs

Load (L) = 320 lbs

Mechanical advantage (MA) =?

Mechanical advantage is simply defined as the ratio of load to effort. Mathematically, it is expressed as:

Mechanical advantage = Load / Effort

MA = L / E

With the above formula, we can obtain the mechanical advantage as illustrated below:

Effort (E) = 80 lbs

Load (L) = 320 lbs

Mechanical advantage (MA) =?

MA = L / E

MA = 320 / 80

MA = 4

Thus, the mechanical advantage is 4
