A cylindrical specimen of a hypothetical metal alloy is stressed in compression. If its original and final diameters are 19.636 and 19.661 mm, respectively, and its final length is 75.9 mm, calculate its original length if the deformation is totally elastic. The elastic and shear moduli for this alloy are 108 GPa and 37.1 GPa, respectively.

Block B starts from rest, block A moves with a constant acceleration, and slider block C moves to the right with a constant acceleration of 75 mm/s2. Knowing that at t = 2 s the velocities of B and C are 480 mm/s downward and 280 mm/s to the right, respectively, use kinematics to determine:

a. The acceleration of A and B

b. The initial velocities of A and C

c. The change in positions of slider C after 3 s.

You have used a IDF curve to calculate the design precipitation for an interstate culvert in Colorado. The stream draining to this culvert originates in the Rocky Mountains. Severe forests fires affected the region after you defined your precipitation design. Due to project delays you manager has asked you to revisit your precipitation estimates. You decided that the wildfires will have a significant effect on the precipitation design storm because they are not locally generate and are usually from major weather systems.
