A heavy rope, 40 feet long, weighs 0.3 lb/ft and hangs over the edge of a building 110 feet high. Let x be the distance in feet below the top of the building. Find the work required to pull the entire rope up to the top of the building. 1. Draw a sketch of the situation. We can look at this problem two different ways. In either case, we will start by thinking of approximating the amount of work done...

1. A 10 ft chain weighs 25 lb and hangs from a ceiling with a 5 lb weight attached to the end. Find the wok done lifting the lower end of the chain and the weight to the ceiling so that they are level with the upper end. 2. Use the method of cylindrical shells to find the volume formula for a sphere with radius r. (in our example we used the disk method. You formula should be the same,...

A body weighing 2 pounds forces hangs from a spring with constant 4 lb / ft....

A body weighing 2 pounds forces hangs from a spring with constant 4 lb / ft. The medium in which the body moves offers a resistance force to movement that is numerically equal to its instantaneous speed. If the weight is released 1/3 feet above its balance position with a downward speed of 9 feet per second, determine the speed at which time it passes through the balance position. Consider negative downward and positive upward magnitudes.

A mass that weighs 32 lb stretches 4/3 ft of a spring. The mass is initially released from rest from a point 1 ft below the equilibrium position, and the subsequent movement takes place in a medium that offers a damping force equal to the instantaneous velocity. Using differential equations find the position of the mass at time t if an external force equal to f (t) = 10cos (t) is applied to the mass

A body weighing 10 pounds forces hangs from a spring with constant 4/5 lb / ft. The medium where the body moves it offers a resistance force to movement that is numerically equal to its instantaneous speed. If the weight is released 5/3 feet above your balance position with a downward speed of 6 feet per second, determine the position the lower the object reaches. Consider negative downward and positive upward magnitudes

A body weighing 128 pounds hangs from a spring with constant 1400 lb/ft. The medium, where the body moves, offers a force of opposition to the movement numerically equal to 15 for its instantaneous speed. If the weight is released 2 feet above its balance position, say how fast it should be initially pushed so that after 6 seconds it reaches the lower limit position. Take the constant of gravity as 32 ft/sec^2.

A lightweight rope is wrapped around a 100-lb drum, passes over a frictionless pulley, and is attached to a weight W (see figure). The coefficient of friction between the drum and the surfaces is 0.50. Determine the maximum amount of weight that can be supported by this arrangement.

A square plot of land has a building 70 ft long and 60 ft wide at one corner. The rest of the land outside the building forms a parking lot. If the parking lot has area 10,200 ft2, what are the dimensions of the entire plot of land? A wire 370 in. long is cut into two pieces. One piece is formed into a square and the other into a circle. If the two figures have the same area, what...

Consider a W30x99 beam (Fy = 60 ksi) that is simply supported, 30 ft. long, and subjected to a point load at the midspan. The point service load consists of 60% live load and 40% dead load. Lateral supports exist at the ends only. Design code to comply with: 2016 AISC LRFD. (a) Determine the maximum point service load P for strong-axis bending assuming Cb = 1.0. (b) Redetermine the maximum point service load P for strong-axis bending considering proper...
