Astepped shaft abc consisting of two solid circular segments is subjected to torques t1 = 20,000 lb-in and t2 = 8,000 lb-in acting in opposite directions. the larger diameter of the shaft is d1 = 2.25 in, and the smaller diameter is d2 = 1.75 in. if the radius of curvature at the transition between the larger and smaller diameters is a quarter circle, calculate the maximum shear stress τmax in the shaft.

gravity

explanation:

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

the answer to this is proletariats.
