Calculated based on the cohesion force suggest that the tensile strength of glass should be 10 GPa. However, a tensile strength of only 1.5% of this value is found experimentally. Griffith supposed that this low value was due to the presence of cracks in the glass. Calculate the size 2a of a crack normal to the tensile direction in a plate.
Given: Young’s Modulus E = 70 Gpa
Surface tension Ye=0.5 J/m^2

1. According to the paper, what does lactate dehydrogenase (LDH) do and what does it allow to happen within the myofiber? (5 points) 2. According to the paper, what is the major disadvantage of relying on glycolysis during high-intensity exercise? (5 points) 3. Using Figure 1 in the paper, briefly describe the different sources of ATP production at 50% versus 90% AND explain whether you believe this depiction of ATP production applies to a Type IIX myofiber in a human....
