5. A solid shaft produced from the 1045 steel in the figure must be 240 cm long and must survive continuous operation for 1.5 YEAR with an applied load of 6000 N. The shaft makes one revolution per minute during operation. What must be the diameter of the shaft that will satisfy these requirements? What must be the diameter if the shaft would work without fracture indefinitely? The maximum stress acting on this type of shaft is o=10.18 L*F/d³

An axial member consisting of two plates each with a width of wa = 390 mm and a thickness of ta = 12 mm is carrying an axial force of P = 22 kN. The axial member is connected to a column by two bolts (diameter of d= 10 mm) three gusset plates with a width of wg = 280 mm and a thickness of tg = 6 mm. What is the average shear stress in the bolts? What is the maximum bearing stress in the connection? In MPa What is the critical normal stress in the axial member?

Problem 5: Questions Determine the capacitance in uF of a parallel plate capacitor having a plate area of 0.03 m and a plate separation of 0.2 um. The dielectric has a dielectric constant of 7. If the Capacitance is C-25mF, what is the distance between the two plates? Use same other values. Determine the inductance of a coil with 400 turns on a core that is 2 cm long and hasa diameter of 1 cm. The permeability (not the relative one) is 0.25 mH/m.

If the maximum force one bolt can withstand is 32505 lbf, how many bolts can be removed from the pressure vessel at the given conditions before the end cap blows off?
