A)Is increased byPZ/e
B)Is increased byPe/Z

D)Remainsunchanged

Question

Quizplus · Accepted Answer

The stress at the extreme top edge is decreased by Pe/Z due to the eccentric placement of the tendon, which creates a moment that counteracts the stress at the top edge.

If the Tendon Is Placed at an Eccentricity E Below
