Suppose the ends of the rail are rigidly clamped at 0°C to prevent expansion.
Calculate the thermal stress in the rail if
its temperature is raised to 34°C. Young's
modulus for steel is 20 x 1010 N/m².
Answer in units of N/m².

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

19 hertz bruh u trippin? ?

Are there options for this?
