Mike and Brandon carry a log that weighs 644N. The trunk is 8.2m long and its weight is evenly distributed (you can consider the center of mass right in the middle). If Mike is 1.5m from the left end and Brandon is 2.9m from the right end, find the force that Mike has to exert to keep the trunk in balance. He considers that both Mike and Brandon exert forces directed completely upwards. Write the result in Newtons with two decimal places.

Abeverage can is made of 3004-h19 aluminum alloy (elastic modulus 69 gpa, tensile yield strength 285 mpa, density 2.72 g/cm^3). the dimensions on the can are approximated as a thin-walled cylinder with a height of 4.83 inches, diameter of 2.60 inches. empty the can has a mass of 14.2 g. determine: a. the wall thickness of the cylinder b. assuming a pinned-pinned condition what is the critical load? c. assuming a fixed-fixed condition what is the critical load?
