1. Durante el despegue, un avión comercial alcanza entre 250 y 290 km/h, dependiendo de distintas variables como la resistencia del viento, la capacidad de peso o el uso de dispositivos de alta elevación. Para el ejercicio tenemos avión se mueve con velocidad de tal manera que, con el aire en reposo, su velocidad es 290 km/h en la dirección 35° noreste, respecto a la horizontal Espacio para el dibujo de los puntos ayb. a. Dibuje el avión junto con el vector velocidad, b. Dibuje las componentes rectangulares vector velocidad. Las componentes rectangulares de la velocidad son: A Vox = 354,02 Vay = -505,59 = 237,55 Voy = 166,33" = 354,02 D. Vex = 237,55 Voy = -166,33 5 B. Vox km C Dax Voy = 505,59 km​

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples? ( be thorough on your answer)
