A 100-N weight is attached to a free end of a metallic wire that hangs from the ceiling. When a second 100-N weight is added to the wire, it stretches 3.0 mm. The diameter and the length of the wire are 1.0 mm and2.0 m, respectively. What is Young’s modulus of the metal used to manufacture the wire?
A 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?
Bruce Lee was famous for breaking concrete blocks with a single karate chop. From slow-motion video, the speed of his 1.50-kg hand descending on a block was estimated to be 15.0 m/s, which decreased to a speed of 0.500 m/s in the 2.50 103 s during which his hand made contact with and broke through the block. The maximum shear stress a concrete block can be subjected to before breaking is 9.50 105 N/m2. a. What was the force exerted by Lees hand on the block? b. If a typical concrete block broken by Lee was 3.00 cm thick and 15.2 cm wide, what is the shear stress experienced by the concrete block? c. Will the concrete block succumb to Lees karate chop?
A vibration sensor, used in testing a washing machine, consists of a cube of aluminum 1.50 cm on edge mounted on one end of a strip of spring steel (like a hacksaw blade) that lies in a vertical plane. The strips mass is small compared with that of the cube, but the strips length is large compared with the size of the cube. The other end of the strip is clamped to the frame of the washing machine that is not operating. A horizontal force of 1.43 N applied to the cube is required to hold it 2.75 cm away from its equilibrium position. If it is released, what is its frequency of vibration?
To measure the static friction coefficient between a 1.40-kg block and a vertical wall, a spring (k = 770 N/m) is attached to the block, is pushed on the end in a direction perpendicular to the wall until the block does not slip downward (see figure). If the spring is compressed by 0.048 m, what is the coefficient of static friction?
A 1.70 kg box rests on a plank that is inclined ut an angle of 63.0° above the horizontal. The upper end of the box isattached to a spring with a force constant of 16.0 N/m, as shown in the figure. If the coefficient of static friction betweenthe box and the plank is 0.26, what is the maximum amount the spring can be stretched and the box remain at rest?

The pole in the figure is a a 90° bend in a power line and is therefore subjected to more shear force than poles in straight parts of the line. The tension in the two wires at the top of the pole is 3.5 × 104 N, and both wires are at an angle of 80° with respect to the pole. The pole is 15 m tall, has an 16 cm diameter and can be considered to have half the strength of hardwood (hardwood has a Young's modulus of 1.5×1010 N/m2 and a shear modulus of 1×010 N/m2). a) First ignore the guy wire (Tgw). Calculate the compression of the pole, in millimeters. b) Still ignoring the guy wire, Find how much it bends in mm to the right. c) Now find the tension in the guy wire used to keep the pole straight if it is attached to the top of the pole at an angle of 30° with the vertical in Newtons. (The guy wire must be in the opposite direction of the bend.)
Humans can bite with a force of approximately 798 N. If a human tooth has the Young's modulus of bone, a cross-sectional area of 1.2 cm2, and is 1.5 cm long, determine the change in the tooth's length during an 7.98 ✕ 102 N bite.
