*10. Go Review Conceptual Example 2 as an aid in solving this problem. An object is at- tached to the lower end of a 100-coil spring that is hanging from the ceiling. The spring stretches by 0.160 m. The spring is then cut into two identical springs of 50 coils each. As the drawing shows, each spring is attached between the ceiling and the object. By how much does each spring stretch? 50-coil spring

What's the answer?
A 4-m long, 150-kg steel beam is attached to a wall with one end connected to a hinge that allows the beam to rotate up and down. The other end of the beam is held in a horizontal position with a cable that makes a 27° angle with the beam and is attached to the wall (see (Figure 1)). a.What is the tension force that keeps this beam in static equilibrium? b. A mass of 75 kg is hung from the beam 3 meters away from the hinge (see (Figure 2)). Now what is the tension force that keeps this beam in static equilibrium? c.What is the vertical component of the force that the hinge exerts on the beam?

6. The static coefficient of friction μs applies to an object of mass m placed on a platter that revolves about a vertical axis at frequency f. Derive an expression for the maximum distance r from the center of the platter at which the object can remain without sliding off the platter.
Jocelyn stood in the middle of a trampoline causing the springs around the edge to stretch. Her identical twin, Jennifer, who has the same mass, joined her in the center of the trampoline. Which statement best describes the effect this had on the springs? A The springs maintained the same amount of displacement. The springs stretched to double the original displacement. C. The spring displacement reduced to half of the original displacement. The springs stretched slightly, but the exact amount cannot be predicted.
A 0.510 kg mass hung from a spring stretches it 0.220 m. II (a) (a) How much (in m) does it stretch two such identical springs if they are hung in parallel, as in (a) of the figure above? (c) How much (in m) does it stretch the two springs if they are hung in series, as in (b) of the figure above? (c) Calculate the effective force (in N/m) constant of a single replacement spring in each case. |N/m (left hand setup) |N/m (right hand setup)
3. A box of books (mass of 7.0 kg) sits stationary on a smooth ramp that is at 45° to the horizontal as shown below. Determine the unstretched length of the spring used to hold this box in place if the spring has a constant of 180 N/m. Question #3 0.40 m 7.0 kg 45° 4. In the diagram below, the two springs have the same spring constant of 250 N/m and an unstretched length of 2.5 m each.

QUESTION 9 A 10-kg block is attached to one end of a horizontal spring on a level, frictionless surface. The other end of the spring is attached to a vertical support. The spring obeys Hooke's law and has a spring constant of k = 160 N/m. A physics student pulls the block outward so that the spring stretches by 40 cm. The student releases the block at time t = 0.00 s. Which of the following equations properly gives the position as a function of time? a. x(t) = (- 1.6 m/s)sin(4.0t) b. x(t) = (- 6.4 m/s2)cos(4.0t) C. x(t) = (10 m)cos(4.0t) d. x(t) = (0.40 m)cos(4.0t) e. x(t) = (4.0 m)cos(0.40t)
