Because Archaea were first found in environments that lacked oxygen or were very hot, acidic, or salty, they were nicknamed “extremophiles.”

In the water cycle, animals return water to the environment by

Q2 subpart At what value of x (in mm) do we have maximum shear stress, and maximum principle stress? Only enter a positive INTEGER number, no units, no space. 

Q1 subpart Write all the process needed to find the maximum bending stress in the beam.(No need to explain the details of calculating support reactions at O and A. Show all the steps after that).  *****************************************************************************  Type step by step, and in order. For each intermediate step: type what you’ll do, what formula you’ll use, and what will be result of that formula. For example: “…Next I’ll use the torsion shear stress formula tau = Tc/J, where T = 400 Nm from the diagram, c = radius of shaft = 0.01m, J = polar moment of inertia = pi*c^4 /2. This gives tau = 254.65 MPa.  Next, I’ll use this tau in….” Consider using bullets.  If you know what you are doing, you only need to type 2-4 ish complete sentences like above. Long essays are not necessary… ******************************************************************************

Q1 statement (10 points)A square cross-section (0.2 m x 0.2m) beam, 12m long, has forces acting as shown. The beam is along x axis. The distributed load 40 kN/m is acting in -y direction. The point load 50 kN is acting in -z direction. The supports O and A are ball and socket joints. They only provide forces, no moments. The ultimate objectiveThe maximum bending stress in the beam.ProcessAnswer the subparts of Q1 below.

Match the following descriptions to the correct reagent.
