Question 4 Consider a certain critical point in a stress element. On a vertical plane, the compressive stress is 115 MPa and the shear stress is 31.5 MPa. There is no normal stress on the horizontal plane. Find the stresses acting on the principal planes and the orientation of principal planes with the horizontal plane. You may need to draw a Mohr circle.

Find p1 and p2

3. An element in plane stress on the fuselage of an airplane (figure part a) is subjected to compressive stresses of magnitude 35 MPa in the horizontal direction and tensile stresses of magnitude 10.5 MPa in the vertical direction (see figure part b). Also, shear stresses of magnitude 12.5 MPa act in the directions shown. Determine the stresses acting on an element oriented at a clockwise angle of 40° from the horizontal. Show these stresses on a sketch of an element oriented at this angle. (a) 10.5 MPa Ţ (b) 35 MPa 12.5 MPa

2. The figure below shows a shaft with pulley and gear. Find the location along the x axis where the normal and shear stresses are the greatest. Create an element drawing of the stress state at this location. Find the principal stresses. Hints:1. the shaft diameter is not given, but you can find the stresses as a function of diameter. 2. Because the shaft is rotating, the maximum normal stress can be determined by using the resultant moment. 1. 622 YA ΤΑ 6 in. - 4 in. Gear/ 600 lb 2000 lb 79 Fp=? 12 in. 200 lb 1 +3 in.-102 D 8 in.
