3. The members of the structure in figure below weigh 280 lb/ft. Determine the smallest diameter pin that can be used at A if the shearing stress is limited to 4200 psi. Assume single shear. B 120

Task 1: Consider a simplified shape of a blood vein branching- similar to the Brachial vein. You like to determine whether this person is having a hypertension (high blood pressure) or a hypotension by determining the pressure in the main vein. Note that a nominal value for the normal pressure for that specific vein is 140 mmHg. If the found value is higher, we can consider the person to be hypertensive. Assume a blood density of 1050 [kg/m³] and a viscosity of 3.5 [Pa.s] Is this a hypertension case? (i.e., is the pressure in the main vein P1 > 140 mmHg? What is the classification of the flow in the main vein, rı = 7.5 mm? (laminar or turbulent)? Show your work. P3 =l.5KPA G=4 mm そ:004 % ri=7.5 mm 2= 3 mm *= 0.02

Explain the Water pump analogy on pg 560 in your own words! (PAGE 560 IS ATTATCHED BELOW) :)

TOPICS: CALCULATION OF CENTER OF GRAVITY  Given: A bar ( from point A to B )of 4 meters in length and weighting 20 kilos where its center of gravity is located in the middle of the bar which is calculated 2 meters away from point A.  You are to load 10 kilos of weight 1 meter away from point A.  Requirements: 1. What is the new Center of gravity when additional 10 kilos are loaded on the bar 2. How much distance that shifted from old Center of gravity to new Center of Gravity 3. Justify the direction of the new Center of Gravity that is showing you?

question c pls For any vector quantity, be sure to always include the magnitude and direction(teacher asked)

Please do not use Ai . I need correct solution in handwritten format

can you solve second problem, i asked for two solutions to two problems

Please explain all parts and which formulas to use

The ambient pressure corresponding to an altitude of 34,615ft and its ambient density corresponding to 31,719ft. What would be the ambient temperature in C?

Help!!! Please answer part A and part B correctly!!! Please!!!
