Without fracture of the femur, determine the maximum height, in cm, from which a 70-kg woman can jump onto just one of her heels, where bare foot and where keeping her leg straight. Assume that all of her stored gravitational potential energy is transfered to strain potential energy in her femur. Take the following values : her femur length, l = 60cm, her femur area, A = 3.5cm2, Youngs modulus for her bone, Y = 1.2x1010 N/m2, and the rupture stress for her bone is σmax = 7.0 x 107 N/m2

An 1150kg automobile has springs with k = 16,000N/m. One of the tires is not properly balanced; it has a little extra mass on one side compared to the other, causing the car to shake at certain speeds. If the tire radius is 42cm, at what speed will the wheel shake most? [Sketch the scenario first]
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.)
