(a) What is the spring stiffness of the entire wire, considered as a single macroscopic (large scale), very stiff spring?ksiN/m One mole of 'nickel (6 × 1023 atoms) has a mass of 59 grams, and its density is 8.90 grams per cubic centimeter, so the center-to-centerdistance between atoms is 2.23 x 10-10 m. You have a long thin bar of 'nickel, 2.3 m long, with a square cross section, 0.10 cm on a side.You hang the rod vertically and attach a 64 kg mass to the bottom, and you observe that the bar becomes 0.721 cm longer. From thesemeasurements, it is possible to determine the stiffness of one interatomic bond in 'nickel.

The triangular block shown in Fig. P-010 is subjected to the loads P = 1600 lb and F = 600 lb. If AB = 8 in. and BC = 6 in., resolve each load into components normal and tangential to AC.
You are working in a factory that produces long bars of copper with a square cross section. In one section of the production process, the bars must slide down a plane inclined at an angle θ = 21.0° to the horizontal. It has been found that the bars travel with too high a speed and become dented or bent when they arrive at the bottom of the plane and must be discarded. In order to prevent this waste, you devise a way to deliver the bars at the bottom of the plane at a lower speed. You replace the inclined plane with a pair of parallel metal rails, shown, separated by a distance ℓ = 2.00 m. The smooth bars of mass m = 1.00 kg will slide down the smooth rails, with the length of the bar always perpendicular to the rails. The rails are immersed in a magnetic field of magnitude B, and a resistor of resistance R = 1.00 Ω is connected between the upper ends of the rails. Determine the magnetic field necessary in your device so that the bars will arrive at the bottom of the plane with a…
A 12.6 inches long key is to be used on a 210 hp, 1200 rpm, slip ring induction motor. The key is 1 in wide and has a depth of 3/4 in. The shaft diameter is 3 7/8 inches. The maximum running torque is 200% of the full-load torque. 1. Determine the maximum compressive (crushing) stress of the key, in psi. 2. Determine the maximum direct shearing stress on the shaft, considering the effect of the keyway, in psi.
My physics class has turned to online due to the COVID-19 and I am having trouble with some of the word problems my teacher gave me to work on. She presented me with: I am contemplating a career change. If I had 500g of stolen gold jewelry, how much energy would I have to add to it to melt it (so that it was not longer recognizable)? Pretend that it is pure gold. Would you be able to show me how to accomplish this problem so I can see the steps? Thank you for your time. John Payton
I am very confused because I was taught that for a series, you would calculate it by adding C1+C2+C3...etc and for parallel, you would calculate it by doing 1/Ctot=1/C1+1/C2+1/C3...etc. but it seems as if you have it the other way around.
A Maxwell’s wheel can be used to store and “recycle” kinetic energy. Suppose that an internal wheel with mass M = 100 kg and radius R =1 ft is used to brake a one metric ton car by converting the vehicle’s linear kinetic energy into rotational kinetic energy. Up to what horizontal velocity of the car will such a system be physically viable if the wheel can sustain a maximum of 4000 rpm (revolutions per minute)?

Let's consider the three atoms composing the molecule now have different masses and coordinate, while the axis of rotation is still z axis that is perpendicular to the xy plane. The first atom has a mass of 142.54 kg, with x coordinate at 3 m and y coordinate at 6 m. The second atom has a mass of 82.55 kg, with x coordinate at 1 m and y coordinate at 6 m. The third atom has a mass of 8 kg, with x coordinate at 5 m and y coordinate at 9 m. What is the moment of inertia in unit of kg m2 with respect to the x axis?

A hydrogen atom of mass 1.67 x 10 27 kg is attached to a very large'protein by a bond that behaves much like a spring. (a) If the vibrational frequency of the hydrogen is 1.0 x 10 14 Hz, what is the “effective” force constant of this spring-type bond? (b) If the total vibrational energy is kT (k is Boltzmann’s constant), approximately what is the classical amplitude of vibration at room temperature? By comparison, the diameter-of a hydrogen atom is about 10 -10 m ?
Consider two immiscible liquids such as water and oil. If a spherical oil molecule of radius r is taken out of the oil phase and placed in the water phase, the unfavorable energy of this transfer is proportional to the area of the solute (oil) molecule newly exposed to the solvent (water) multiplied by the interfacial energy, i, of the oil-water interface. The interfacial energy of the bulk cyclohexane-water interface is i = 50 mJ m-2, and the radius of a cyclohexane molecule is 0.28 nm. Using Boltzmann distribution, estimate the solubility of cyclohexane in water at 25 C in units of mol L-1.The concentration of water in water phase is 55.5 mol L-1.
