Perform this experiment 5 times with each object.Note: The wooden toothpick should slide lengthwise (i.e., not roll) downthe meter stick.4/63.<> DATA ANALYSIS1. Calculate the mean of the height for each object. Enter your result todata table2. Using your measurement data, calculate the standard deviation of theheight for each object3. Calculate the relative error of your measurement of the height for eachobject.4 Measure the mass of the coin, a wooden toothpick and s clothes button (inthe internet find the mass of the object you are using).5. Drawing and using the free-body diagram solution method, derive the equationfor T for an object of mass m being slide an incline (>0) at a constant velocity.Set the coordinate system such that the x-axis is parallel to the incline.6. Using the Pythagorean Theorem, the length of a meter stick and themeasured height of the edge of the meter stick when each object juststarted to slide, calculate the base of the ramp for each object.7. Using the result that the coefficient of friction at the angle ofrepose equals theratio of the height of the ramp divided by the base of the ramp, calculatethe coefficient of friction for the button, the coin and the wooden toothpick8. Find on the internet or in a library (eg. the CRC Handbook of Chemistryand Physics) the ranges of coefficients of friction expected for wood onwood, plastic on wood, metal on wood (or vice versa).9. Calculate the percent error of your experimental resultPART TWOK

A dancer is standing on one leg on a drawbridge that is about to open. The coefficients of static and kinetic friction between the drawbridge and the dancer's foot are μs and μk, respectively. n⃗ represents the normal force exerted on the dancer by the bridge, and F⃗g represents the gravitational force exerted on the dancer, as shown in the drawing.(Figure 1). For all the questions, we can assume that the bridge is a perfectly flat surface and lacks the curvature characteristic of most bridges. Before the drawbridge starts to open, it is perfectly level with the ground. The dancer is standing still on one leg. What is the horizontal component of the friction force f⃗? (Express your answer in terms of some or all of the variables n, μs, and/or μk.) (Figure 2). The drawbridge then starts to rise. The dancer continues to stand on one leg. The drawbridge stops just at the point where the dancer is on the verge of slipping. What is the magnitude f of the frictional force now? (Express…

Casting molten metal is important in many industrial processes. Centrifugal casting is used for manufacturing pipes, bearings, and many other structures. A variety of sophisticated techniques have been invented, but the basic idea is as illustrated in Figure P4.35. A cylindrical enclosure is rotated rapidly and steadily about a horizontal axis. Molten metal is poured into the rotating cylinder and then cooled, forming the finished product. Turning the cylinder at a high rotation rate forces the solidifying metal strongly to the outside. Any bubbles are displaced toward the axis, so unwanted voids will not be present in the casting. Sometimes it is desirable to form a composite casting, such as for a bearing. Here a strong steel outer surface is poured and then inside it a lining of special low-friction metal. In some applications, a very strong metal is given a coating of corrosion-resistant metal. Centrifugal casting results in strong bonding between the layers. Suppose a copper sleeve of inner radius 2.10 cm and outer radius 2.20 cm is to be cast. To eliminate bubbles and give high structural integrity, the centripetal acceleration of each bit of metal should be at least 100g. What rate of rotation is required? State the answer in revolutions per minute.
