Una lancha se desplaza con una velocidad de 10 m/s cuando el motor deja de funcionar debido a la falta de gasolina. A consecuencia de esto, la resistencia aerodinámica, la aceleración subsecuente está dada por la ecuación a=-0.05 v^2 , en donde la velocidad esta dada en m/s

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

Hydraulic fluid with a sg. of 0.78 is flowing through a 1.5 in. i. d. pipe at 58 gal/min. the fluid has an absolute viscosity of 11.8 x 105 lbf-sec/ft2. is the flow laminar, turbulent or within the critical range? give both a numerical reynolds number and a term answer.
