An officer suspects that Mary is selling drugs out of her home. When the officer knocks on the door, Mary's husband, John, answers the door, and the officer asks permission to search their home. Which circumstance would be a violation of Mary's Fourth Amendment right? John gives consent, but Mary immediately comes to the door and refuses permission. The officer continues the search regardless. John tells the officer Mary is at work, and refuses permission for the officer to search. Because Mary isn't present, the officer searches the apartment regardless. John tells the officer that Mary is at her parent's house, and gives him permission to search the apartment. John gives consent to search the apartment, and although Mary did not want the search to continue, she does not protest because she is afraid she will look guilty.

You have been asked to help a welder who is trying to weld mild steel plates to form a tank. He needs help making sure that the sides are vertical. Describe how you could use Pythagoras' theorem to ensure the sides are vertical. X Using Pythagoras' theorem is to ensure that the sides of the tank are vertical by checking for right angles at the corners of the tank. • start by marking the corners of the tank where you want to ensure the sides are vertical and these should be the points where the steel plates meet at right angles. • measure the length of one side of the tank and lets call it "a" and measure the lenght of the other side of the tank and lets call it "b" • calculate the diagonal by using the Pythagora's theorem which states that the squre of the length of the hypotenuse (the diagonal) of a right triangle is equal to the sum of the squares of the two sides. In this case the diagonal is the hypotenuse. And calculate the length of the diagonal (let's call it "c") using the theorem: $$c^2 = a^2 + b^2$$. • measure the diagonal using tape measure or ruler, measure the calculated diagonal length "c" on the tanks surface, make sure the measurement from corner to corner is equal to "c". • checking for the right by verifying that the sides are perpendicular (from a 90-degree angle). If the sides are perpendicular, it means the tank's sides are vertical. • adjust as necessary if you find that the side are not perpendicular, you may need to make adjusments to the steel plates by shifting them until the right angles are formed. Using Pythagora's theorem and the measurements, we can be confident that the sides of the tank are vertical, which is crucial for ensuring the tank's structural integrity. This method helps us achieve accurate right angles at the corners, and to ensure that the structures are built correctly.

The load bar of negligible weight is screwed in place between the walls of the truck bed in order to keep loads from shifting as shown in (Figure 1). Determine the torsional moment $M$ that must be applied to the center of the bar so that it produces a compression in the bar of 75 lb. The square-threaded screw at A has a lead of 0.2 in. and a radius of 0.5 in., and the coefficient of static friction between the bar and the screw is $\mu_s = 0.3$. Express your answer in pound-inches to three significant figures. $M = 33.3$ lb\text{-}in Part B Also, what amount of horizontal force $F$ must be applied to the center of the bar to pull it out? The coefficient of static friction between the walls of the truck and the end pads is $\mu_s = 0.7$. Express your answer in pounds to three significant figures. $F = 105$ lb
