Group Problem: You are planning to build a log cabin in Northern Minnesota on a remote hill with a beautiful view of the setting sun. You will drag the logs up a long sometimes rocky hill to the building site by means of a rope attached to a winch. You will need a rope for this job so you aim to know how much weight the rope would safely support. You are operating on a tight budget so matching the rope strength would be a cost saver. You know that the logs are heavy, and estimate the heaviest as 1,000 lbs. From maps you verify the hill is steeped at an angle of = 70° with respect to the vertical, and you estimate a coefficient of kinetic friction between a log and the earthen hill as 0.5. When pulling a log you will ensure that the uphill acceleration is never more than 3.0 ft/s². The maximum recommended load is th of the nominal strength for the ropes considered as stated on the product labels, you have three ropes in mind: 12 kN, 18 kN, & 24 kN. Which one of these three rope…

Learning Goal: To be able to find the center of gravity, the center of mass, and the centroid of a composite body. A centroid is an object's geometric center. For an object of uniform composition, its centroid is also its center of mass. Often the centroid of a complex composite body is found by, first, cutting the body into regular shaped segments, and then by calculating the weighted average of the segments' centroids. An object is made from a uniform piece of sheet metal. The object has dimensions of a = 1.25 ft, where a is the diameter of the semi-circle, b = 3.71 ft, and c = 2.30 ft. A hole with diameter d = 0.750 ft is centered at (1.09, 0.625). Figure kd- J = 0.737 Find y, the y-coordinate of the body's centroid. (Figure 1) Express your answer numerically in feet to three significant figures. View Available Hint(s) ΑΣΦ Submit Previous Answers vec 3 X Incorrect; Try Again; 2 attempts remaining ? ft

Learning Task 2: Changes in momentum happen every time. A fast-moving car when suddenly stopped might have damaging effects not only to the vehicle itself but also to the person riding it. Various devices have been installed in vehicles to ensure the safety of the passengers. Can you think of some safety devices installed on vehicles (public/private)? Name at least five (5) of them.

Learning Goal: A column with a wide-flange section has a flange width b = 200 mm , height h = 200 mm, web thickness tw = 8 mm , and flange thickness tf = 12 mm (Figure 1). Calculate the stresses at a point 75 mm above the neutral axis if the section supports a tensile To calculate the normal and shear stresses at a point on the cross section of a column. normal force N = 2.9 kN at the centroid, shear force V = 4.6 kN, and bending moment M = 4.8 kN • m as shown (Figure 2). The state of stress at a point is a description of the normal and shear stresses at that point. The normal stresses are generally due to both internal normal force and internal bending moment. The net result can be obtained using the principle of superposition as long as the deflections remain small and the response is elastic. Part A - Normal stress Calculate the normal stress at the point due to the internal normal force on the section. Express your answer with appropriate units to three significant figures. > View…

This is an engineering problem and not a writing assignment. Please Do Not Reject. I had other engineering tutors on bartleby help me with problems similar to this one. This problem must be presented in a logical order showing the necessary steps used to arrive at an answer. Each homework problem should have the following items unless otherwise stated in the problem: a. Known: State briefly what is known about the problem. b. Schematic: Draw a schematic of the physical system or control volume. c. Assumptions: List all necessary assumptions used to complete the problem. d. Properties: Identify the source of property values not given to you in the problem. Most sources will be from a table in the textbook (i.e. Table A-4). e. Find: State what must be found. f. Analysis: Start your analysis with any necessary equations. Develop your analysis as completely as possible before inserting values and performing the calculations. Draw a box around your answers and include units and follow an…

Part A Learning Goal: To apply the principle of moments and the principle of transmissibility. What is Mp,, the contribution to the moment about point O made by the x component of the force F at point A? What is MF., the contribution to the moment about point O made by the y component of the force F at point A? What is the total moment M due to the force F about point O? Assume that moments acting counterclockwise about point O are positive whereas moments acting clockwise are negative. As shown, a rope is attached to a l= 19.0ft high shed that is to be relocated. A man pulls on the end of the rope at point A; the rope is attached to the shed at point B. (Figure 1) As the man pulls on the rope, it creates an angle 0 with the horizontal. The end of the rope is located at x = 15.0ft from the shed and y = 5.00ft off the ground. The man pulls on the rope with a force of magnitude F = 70.0lb Express your answers numerically in pound-feet to three significant figures separated by commas. >…

Learning Goal: To describe the shape and behavior of cables that are subjected to concentrated and distributed loads. Part A Structures often use flexible cables to support members and to transmit loads between structural members. Because a cable's weight is often significantly smaller than the load it supports, a cable's weight is considered negligible and, therefore, not used in the analysis. In this tutorial, cables are assumed to be perfectly flexible and inextensible. Thus, once the load is applied the geometry of the cable remains fixed and the cable segment can be treated as a rigid body. Cables of negligible weight support the loading shown. (Figure 1) If W, = 85.0 N , W, = 510 N, YB = 1.40 m, yc = 2.80 m, yp = 0.700 m, and zc = 0.850 m, find zg.

Are you as strong as a horse? Purpose: To understand the concept of work and power and to calculate the power generated by yourself or a friend. Materials: A tape measure, stairs, and a stopwatch, cell phone, or wristwatch. Key Physics Concept: Power is the rate of doing work. Power can be calculated by dividing the work done by the time it takes to do the work; in this case we will do work against gravity on a stair case (you may add your power in doing pushups to test your arm power). Can you guess what your peak horsepower is? You may do the stairs one at at time or multiple stairs at a a time; whatever is most safe and efficient for you. Procedure: Observations: Analysis: Conclusions: Application: 1. Will your hp change if you performed the activity for a longer duration (for example, climbed the CN tower staircase)? In what way? Explain. 2. Research the horsepower generated by a car. How does the average person's peak power rating compare to it? How many average people would it…

Case Study: Paula’s Pain Paula has worked for Brindle Corporation for 3 years.  During this time, she has worked as a machine operator/cell leader in various work cells.  Recently, the plant went to mandatory 12-hour shifts and plans to remain on this schedule for several months. Paula’s present work cell is manufacturing 3-inch diameter exhaust tubes that are made from stainless steel.  These tubes get a hole punched in them, a flange welded on, and burrs ground off.  The pipe then gets placed into a gage to check that it was made correctly.  (The tubes weigh about six pounds.) Paula has been performing the welding operation.  She leans into the machine and loads the part into a fixture then positions the flange.  Both pieces are clamped (using hand clamps) into position and the machine is cycled by depressing two palm buttons. The gaging operation requires placing the finished part into the gage and clamping it (using hand clamps) into place. A pin is depressed to verify the position…
