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?
What can you say about the velocity of a moving body that is in dynamic equilibrium?
Figure Q3(b) shows a uniform bar AB of mass = 8 kg hinged at point C. Point A is connected to a spring to maintain the bar in vertical direction, and the stiffness k = 500 N/m. If point A is displaced counter-clockwise by a small angle θ = 3.5 degree and released, (iii) Determine the maximum velocity and acceleration at point A.
One of the scientists, in trying to represent the relationship between the oil stiffness and the mechanical energy lost, writes down the equation 2 Elost = CS2, where C is a constant with appropriate units. Another scientist points out that this equation cannot be correct. Give two reasons why the equation cannot be correct.
An ideal spring hangs vertically. When a 453 g object is hung from the bottom end, and lowered gently, the spring stretches 5.58 cm. How much would be the spring have stretched, in cm, if the mass of the object had been 560 g instead? x'=?
A ride at an amusement park attaches people to a bungee cord, pulls them straight down to the ground, and then releases them into the air. When they are pulled to the ground, the bungee cord (which has a stiffness constant of 35 N/m) is stretched 100 m beyond its unloaded length. What restraining force is required to hold a man with a mass of 100 kg to the ground just before he is released? (Recall that g = 9.8 m/s2)
When a force F acts on a linear spring, the elongation x of the spring is give by F=kx, where k is called the stiffness of the spring. Determine the dimention of k in terms of the base dimention of an absolute (MLT) system of units

A 1300-kg car rolling on a horizontal surface has speed v = 45 km/h when it strikes a horizontal coiled spring and is brought to rest in a distance of 3.1 m . What is the spring stiffness constant of the spring? Express your answer using two significant figures.
While playing with one of Dr. D’s latest devices Perry takes the device that has a mass of 1.75kg and uses it to compress a spring with an unknown stiffness k by 0.900m. The device is released from rest and slides across a horizontal rough spot 2.15m long with a coefficient of kinetic friction 0.625. The device then compresses a second spring with the same stiffness k by 0.450m. Find the stiffness of both springs.
