An element is subjected to plane stress. By rotating 20 degrees in the clockwise direction from its original position, the element can reach its principal stress state. Which rotation of the element from its original position can reach the state of maximum in-plane shear stress?A. 25 degrees in the counterclockwise directionB. 70 degrees in the clockwise directionC. 45 degrees in the clockwise directionD. 45 degrees in the counterclockwise directionE. 70 degrees in the counterclockwise directionF. 25 degrees in the clockwise direction

Apossible long term health effects of stress would be work

Are there options for this?

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.

Iwould say the answer is d
