A person ties a rock to a string and whirls it around in a circle such that sometimes the rock is going straight upward and sometimes the rock is going straight down (the plane of the circle is perpendicular to the horizon). They whirl the rock at the minimum speed (constant in time) such that the string is always taut (no sag). If they were to use a longer string, they would have to whirl the rock at a O higher velocity. O lower velocity. O the same velocity.

The next several problems utilize the same data given in this problem statement. I suggest you glance over the next few problems, so that you have an idea of the items you will need to calculate. You may determine that you calculate the items in an order other than that given on the test (doing this is OK!). BUT, be sure you look at EACH problem and provide the answer to that particular problem. Consider the bracket shown in Fig-3. If: • F1 = 10 lb @ -90° • a = 2 ft • b= 4 ft • C = 1 ft then, what is the magnitude of the vertical reaction at point 'A?

The system shown is in static equilibrium and motionless. Consider the 10 kN force as "the load" on the system. • The coefficient of static friction at a rope/shaft interface is 0.25. • The coefficient of kinetic friction at a rope/shaft interface is 0.16. NOTE: • Submitted responses shall be to 4 significant figures. Do NOT use scientific notation. Find: 8. The angle of wrap around the upper-left shaft is 9. The angle of wrap around the lower-right shaft is 10. The maximum magnitude of the force P that will not initiate upward motion of the load is rad. _kN. 11. The minimum magnitude of the force P that will not initiate downward motion of the load is _kN.
