The beam in Problem 5.61 has a circular cross section with a diameter of 40 mm, has a length of 2.00 m, and is made of a steel (E = 200 GPa) having a working stress limit of 140 MPa.

a. Determine the magnitude of w that will produce this limiting stress.

---

b. How much would the stress in the beam be increased for the same value of w if the left end of the beam deflects 5.00 mm before making contact with the support?

Problem 5.61

The beam in Figure P5.61 is fixed at the right end and simply supported at the left end. Determine the reaction R at the left end, assuming that the length L of the beam is large compared with its depth.
