Which of the following statements are correct about a cantilevered beam with point load acting on the extreme end of the beam?

(a) Shear stress along the length of the beam increases linearly

(b) Shear stress along the length of the beam deceases linearly

(c) Shear stress along the length of the beam decreases exponentially

(d) Shear stress along the length of the beam remains constant

This question was posed to me in my homework.

Asked question is from Shear Force & Bending Moment topic in division Beams and Frames of Finite Element Method
