Suppose you have a stack of 17 identical steel bars (steel bars have a mass of 1.00kg each). You are required to pull out bar number 16 from the stack (counting from the top of the stack down). Assuming that your assistant holds all other bars in place. If the coefficient of friction between steel and steel is 0.750, how hard do you have to pull (in N)?
Zoologists have studied the mechanics of locust jumping. When a locust jumps, as depicted in the figure, the resultant force R exerted by the hind legs is the sum of two forces. The first force W acts directly downward to support the locust's weight, which is about 0.02 newton. The second force F is for the takeoff; its magnitude is about 0.29 newton, and the direction makes an angle of 55° with the horizontal. W 55° Find the magnitude of the resultant force R = F + W. (Use decimal notation. Give your answer to three decimal places.) magnitude of resultant force R: newton
Four acrobats of mass 72.0 kg, 68.0 kg, 62.0 kg, and 55.0 kg form a human tower, with each acrobat standing on the shoulders of another acrobat. The 72.0-kg acrobat is at the bottom of the tower. (a) What is the normal force acting on the 72.0-kg acrobat? (Enter the magnitude only.) N (b) If the area of each of the 72.0-kg acrobat's shoes is 390 cm², what average pressure (not including atmospheric pressure) does the column of acrobats exert on the floor? Pa (c) Will the pressure be the same if a different acrobat is on the bottom?
A particular bridge, with a length L, consists of a horizontal slab with a weight of 50.0 kN, with the weight uniformly distributed. The slab is held up by one support 20% of the way across the bridge, and a second support 80% of the way across the bridge. As shown in the picture, a truck with a weight of mg = 12.0 kN is driving from left to right across the bridge. 0.4L horizontal slab mg| 0.2L 0.2L (a) Once the truck is completely off the bridge, how much force will the left support exert on the horizontal slab? We're looking for an answer in kilonewtons (kN), which is what values are given in above. kN (b) When the truck is at the position shown, where its full weight can be taken to act at a point 40% of the way across the bridge, calculate the force that each support exerts on the horizontal slab. We're looking for two answers-the value of each of the support forces. The force exerted by the left support is kN. The force exerted by the right support is kN. (c) As the truck…

In about 1915, Henry Sincosky of Philadelphia suspended himself from a rafter by gripping the rafter with the thumb of each hand on one side and the fingers on the other side (see the figure). Sincosky's mass was 83.0 kg. If the coefficient of static friction between hand and rafter was 0.710, what was the least magnitude of the normal force on the rafter from each thumb or opposite fingers? (After suspending himself, Sincosky chinned himself on the rafter and then moved hand-over-hand along the rafter. If you do not think Sincosky's grip was remarkable, try to repeat his stunt.)
