- An aluminium (=2.7g/cm3) wire is suspended from the ceiling and hangs vertically. How long must the wire be before the stress at its upper end reaches the proportionality limit, which is 8.0107N/m2 ?arrow_forwardIn order to get his car out of the mud, a man ties one end of a rope to the front bumper and the other end to a tee 15 m away as shown below. He then pulls on the center of the rope with a force of 400 N, which causes its center to be displaced 0.30 m, as shown. What is the force of the rope on the car?arrow_forwardIf an odd number of forces act on an object, the object cannot be in equilibrium.arrow_forward
- A brass wire and a steel wire, both of the same length, are extended by 1.0 mm under the same force. Is the cross-sectional radius of the brass wire more, less, or equal to the cross-sectional radius of the steel wire? Explain. Youngs moduli for brass and steel are 1.0 1010 N/m2 and 2.0 1011 N/m2, respectively.arrow_forwardIs it possible to apply a force at P to keep in equilibrium the structure shown? The weight of the structure is negligible.arrow_forwardA steel cable 2.00 m in length and with cross-sectional radius 0.350 mm is used to suspend from the ceiling a 10.0-kg model aircraft that is flying in a horizontal circle with an angular speed of 6.00 rad/s. What is the strain produced in the cable?arrow_forward
- A cook holds a 2.00-kg carton of milk at arm's length P8.19). What force FB must be exerted by the biceps muscle? (Ignore the weight of the forearm.) Figure P8.19arrow_forwardA horizontal force F is applied to a uniform sphere in direction exact toward the center of the sphere, as shown below. Find the magnitude of this forcee so that the sphere remains in static equilibrium. What is the frictional force of the incline on the sphere?arrow_forwardA cook holds a 2.00-kg carton of milk at arm's length P8.19). What force FB must be exerted by the biceps muscle?

- A uniform horizontal strut weighs 400.0 N. One end of the strut is attached to a hinged support the wall and the other end of the strut is attached to a sign that weighs 200.0 N The strut is also supported by a cable attached between the end of the strut and the wall. Assuming that the entire weight of the sign is attached at the very end of the s find the tension in the cable and the force at the hinge of the strut.arrow_forwardExplain the need for tall towers on a suspension bridge to ensure stable equilibrium.arrow_forwardOne end of a uniform 4.00-m-long rod of weight Fg is supported by a cable at an angle of = 37 with the rod. The other end rests against the wall, where it is held by friction as shown in Figure P12.23. The coefficient of static friction between the wall and the rod is s= 0.500. Determine tile minimum distance x from point A at which an additional object, also with the same weight Fg can be hung without causing the rod to slip at point A.arrow_forward
