3. Assume the plane stress state: ơ1 = 0, 02 = 20, T12 = 15 (all stresses in ksi). If oz alone is increased until the maximum shear stress t1, in the material reaches ±20 ksi, what is the value of o, at this point? HINT: this is relatively easy to figure out if you construct a Mohr's circle for the initial stress state and then consider what happens if o, is replaced with Ao2 and you solve for A when the maximum shear stress (from the circle geometry) reaches ±20 ksi.

4.3. Assessing Risk of Aneurysm Rupture: Studies suggest that the maximum allowable stress (failure strength) for the wall tissue in an aortic aneurysm is o = 220 kPa, after accounting for factor of safety. A physician wants your expert opinion on the maximum diameter that an aortic aneurysm in a hypertensive patient (BP 200/90 mmHg) could be allowed to grow to before rupture becomes imminent. The wall thickness may be assumed to remain unchanged at t = 1.2 mm. State your answer in millimeters of diameter. INDBER

An enormous and expensive artwork with mass 42.8 kg is mounted on a wall with four heavy-duty steel bolts, each with a diameter of 5 mm. There is 10 cm gap between the painting and the wall. The shear modulus of the steel bolt is 9.0 x 10^10 N/‘m^2. Find the shear stress on the bolts and find the resulting vertical deflection of the bolts.
