Match the stages of fire growth with the type of automatic detectors designed to sound an alarm at that stage.

 You have noticed a bacteria that has lots of sterols in its plasma membrane and noticed the absence of the cell wall. These bacteria are called 

  BONUS QUESTION: This one requires thorough analysis. No help will be given for this question. What is the concentration of bacteria IN THE PLATE  (with 1 ML sample) with 6 colonies after plating?

A culture started out with five microbes. After five generations, how many microbes are in the culture? 

Two toy blocks are stacked to form a tee-shape. Each block has dimensions a = 15.1 mm and b = 45.3 mm. Determine the vertical distance from the table to the centroid of the shape.

A 43-N eagle sits on a tee-shaped post that has a diameter of 45 mm. Determine the magnitude of the largest normal stress in the vertical part of the post. Let a = 0.40 m be the distance from the eagle to the centroid of the post.

A cylindrical beam supports a shear force of 15.4 kN. The outside diameter is 58 mm, and the wall thickness is 4 mm. Determine the maximum horizontal shear stress in the beam.

A cylindrical beam supports a shear force of 15.2 kN. The outside diameter is 48 mm, and the wall thickness is 5 mm. Determine the maximum horizontal shear stress in the beam.

A 1,480-lb dinosaur stands on a simply-supported beam. Determine the maximum bending moment in the beam. Let a = 11.1 ft and b = 6.8 ft.

Five toy blocks are glued together to form a beam that supports a shear force of 137 N. Each block has dimensions a = 18 mm and b = 54 mm. Determine the horizontal shear stress in the glue between blocks (4) and (5).
