A bicycle wheel is assembled with each spoke pre-tensioned to a tensile force of 95 lbf. The diameter of each spoke is d = 0.0787 in. After the wheel is assembled, a strain gauge is applied to a representative spoke so that the gauge reads zero strain in the pre-tensioned condition. The figure below shows one cycle of strain readings as the wheel rotates through one revolution in use. Zero degrees corresponds to the spoke being between the hub and the ground (i.e., at the six o'clock position). 50 -50 -100 -150 -200 -250 -300 -150 -100 -50 50 100 150 Spoke position in degrees He, microstrain

- Determine the resulting maximum value of the normal stress. Specify the orientation of the plane on which these maximum values occur. **The answer is tensile stress is 0 ksi at 90 degrees. **The answer is compressive stress is 7 ksi at 0 degrees. Can you explain how that is? This was my thought process: I know that tensile would be zero because the force P is actually going inwards and not outwards. I know that means that there would be a compressive force. I am confused on the angles, how is a tensile force going 90 degress if there technically is no force in the tensile direction. And how is there a compressive force at 90 degrees if there is a stress? thank you!Find the strain proportions (ɛ1:E2:E3) that existed in a forming process where O3= 0.
