A 60.0 cm, uniform, 50.0 N
shelf is supported horizontally by two
vertical wires attached to the sloping
ceiling (Fig. ). A very small
25.0 N tool is placed on the shelf midway
between the points where the
wires are attached to it. Find the tension
in each wire. Begin by making a
free-body diagram of the shelf.

- The figure below shows a bird feeder that weighs 101.1 N. The feeder is supported by a vertical wire, which is in turn tied to two wires, each of which is attached to a horizontal support. The left wire makes a 60° angle with the support, while the right wire makes a 30° angle. What is the tension in each wire (in N)? A bird feeder is suspended from a vertical wire. The top of the wire is tied to two other wires. The left and right wires go up and to the left and up and to the right, respectively, from the connection point to a horizontal support. The left wire makes an angle of 60° with the support. The right wire makes an angle of 30° with the support. left wire Nright wire Nbottom wire NPA BY 200 lb -y 2 ft 2 ft 3 ft The slab shown is supported by vertical cables at points A, B, and C.

- Given the diagram shown with a ramp angle of 20° and Masses m1 and m2. If m1 = 4 times m2. What is the minimum coefficient of static friction required between m1 and the ramp for equilibrium?Three main forces that act on the patella, and are shown on the diagram below. These forces are the quadriceps muscle force (FQ), the patella ligament force (FPL), and the patellofemoral joint reaction force (FPF). The angles a and ẞ are with respect to a line that is perpendicular to FPF. Assuming a = 10°, ẞ = 30°, and FQ = 4000 N, use the equations for static equilibrium to calculate the FPL in Newtons. Round to an integer, such there is no need for a decimal. FQ FPF FP BConsider two geometrically identical marbles stacked in a container as shown. The radius of each of the marbles is R. while the width of the container is 2.9R. The marble at the top has a weight 0.78 N while the weight of the lower marble has a weight of 0.82 N. What is the magnitude of the normal force at point B? Express your answer in Newtons and with two decimal places. C А В
- A setup similar to the one shown in the figure below is often used in hospitals to support and apply a horizontal traction force to an injured leg. (Let m = 5.25 kg and 8 = 75.0°.)

Additional Materials еВookA skydiver weighing 65 kg jumps out of a helicopter hovering at a height of 3 kilometers. Assume a cross-sectional area of 0.5 square meters. After thirty seconds of free fall, the skydiver deploys the parachute and the cross-sectional area becomes 40 square meters. Reproduce the model for the skydiver in Excel or VenSim. In VenSim you may have to make At quite small in order not to throw an error. Because you reach terminal velocity relatively quickly your answer should not be particularly sensitive to the value of At you choose. What is the skydiver's terminal velocity without the parachute? meters/second What is the skydiver's terminal velocity with the parachute? meters/secondThe block shown in (Figure 1) has a mass of m = 75 kg, a height H = 1.1 m, and width L = 1.6 m. It is resting on a ramp that makes an angle 0 = 34° with the horizontal. A force P is applied parallel to the surface of the ramp at the top of the block. What is the maximum force that can be applied without causing the block to move? The coefficient of static friction is μs = 0.42, and the center of mass of the block is at the center of the rectangle.
