Which hormone is primarily responsible for maintaining the endometrium during the late part of the cycle (i.e. post-ovulation) each month in anticipation of implantation by an embryo?
1. Which of the following are linear combinations of \( \mathbf{u}=(0,-2,2) \) and \( \mathbf{v}=(1,3,-1) \) ? a. \( (2,2,2) \) b. \( (0,4,5) \) c. \( (0,0,0) \)
The following pipe connection is subjected to a pure bending moment of 12 kip*in. The two pipe flanges are connected with 12 bolts around a circle of 8 inches in diameter. The neutral axis for the bending is shown in the figure below. The force experienced by each bolt can be represented with this formula: $F_{b,i} = F_{max} \cdot R \cdot \sin(\theta)$ The bolt size is 1.5" for the tensile area diameter and have a proof strength of 30.5 ksi. The Young's modulus for the bolt material and the pipe material are 29 and 14 MPsi respectively. The bolts were preloaded to 75% of their proof strength. For the worst bolt case, find: a) The separation safety factor. b) The bolt safety factor. Note: for $F_{max}$ calculation purposes pretend the bottom half bolts produce a compressive force. (Sol: a) 107.6; b) 1.33)
