The principal stresses at a point across two perpendicular planes are 75 MN/m? (tensile) and 35 MN/m? (tensile). Find the normal, tangential stresses and resultant stress and its obliquity on a plane at 200 with the major principal plane by Analytical method.

What does the each point on Mohr’s circle represent?

for 2 can you please do a sketech veriation of it?

I didn't understand how you find the angle Alpha = 21.63

Part I. Shorter problems focused on the fundamentals a. For the image at the right, the coordinate angles are a = 57°, ẞ= 121°, y=49°, and the point along a-a is (15,-6,3). What is the angle between lines a-a and b-b? Z b-b B LL F a (x,y,z) a-a Y b. If the magnitude of the force, F-3121bf, what is the magnitude projected along the a-a axis? y

Question 16 Here is a way we can estimate the distance from the earth to the moon. When the moon is seen at its zenith at a point A on the earth, it is observed to be at the horizon from point B. Points A and B are 6152 miles apart and the radius of the earth is 3960 miles. 20 Earth 0= B a) Calculate the angle in radians. (Round your answer to 5 decimal places.) d= ? v Moon Details b) Estimate the distance from point A to the moon using your angle from part a). (Round your answer to the nearest thousand.) ?
