changes in What Have I Learned So Far? There are two carts hanging on a string that weigh 5 kg and 10 kg through a pulley as shown in the given figure. 10.0 kg 5.0 kg 30% a frictionless 1. What is the tension along the string? 2. Describe the acceleration of the two blocks. 3. Suppose the system is initially at rest with the heavier block at 2.5 meters above the ground. How long will it take for this block to reach the ground? 4. What is the velocity of the heavier block before it hits the ground?

A 10-inch industrial fire hydrant has a 6-inch diameter fire hose with a 0.77-inch nozzle that discharges a water jet into the air on the right end. The pressure in the hose is 60 psi and the flow rate is 2,236 GPM. What is the resultant axial force (net value only) the water exerts on the nozzle, in pounds? 6-in. Oa. 6,873 pounds Ob. 8,473 pounds Oc. 10,854 pounds Od. 12,926 pounds

Two angles joined by 7/8-in. rivets form a steel tension member. The gross area of the member is 6 sq. in. and the thickness of the material is 3/8 in. The net area of the member may be found by allowing for one rivet hole in each angle. What is the maximum load that may be carried safely by the member if the allowable stress is 16,000 psi. a. 73,000 lb b. 48,000 lb c. 99,000 lb d. 84,000 lb

Yelp Dog Food produces specialized dog foods in 1-pound packages. The amount of dog food in each package should be 1 pound, and Yelp has determined that the standard deviation of the machine filling these packages is half an ounce, and the confidence interval is 14.85% (z = .1872). In order to confirm that the machine is operating properly, Yelp takes 16 sample bags every hour and weighs them. The means of these 16 bags for an 8-hr shift is given below. 1 2 3 4 5 6 7 8 0.98 1.01 0.97 1.03 1.01 0.94 1.02 1.02 NARREND   How many, if any, of the hours were out of control? 0 2 3 7
