A cantilevered rectangular beam has witl

given dimensions and is subject to

completely reversing load of $1000$ lb $.$ an

$-1000$ lb $.$ If the bar is made of a materia

whose tensile strength is $2000$ ps

compute the following

a$.(5$ pts$)$ Draw FBD and compute the reaction forces at the support

b$.(10$ pts$)$ Compute the maximum completely reversed stress in the beam, show all steps for full

credit

c$.(5pts)$ Clearly indicate the location of the maximum stress

d$.(5$ pts$)$ Calculate the fully corrected endurance limit

e$.(10$ pts$)$ Estimate the number of cycles to failure.
