Suppose the ends of a 27-m-long steel beam are rigidly clamped at 0°c to prevent expansion. the rail has a cross-sectional area of 35 cm^2. what force does the beam exert when it is heated to 39°c? (αsteel = 1.1 × 10^−5/c°, ysteel = 2.0 × 10^11 n/m^2).

F = 1.58*10^{11} N

Explanation:

given data:

length of steel beam = 27 m

cross sectional area of rail = 35 cm

Degree celcius

change in length of steel beam is given as

            m

Young's modulus is

F = 1.58*10^{11} N

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
