2) Help to find only (b) the value of the torsional constant k of the fiber.Don't need to find the expression of the torsional constant. A thin metal disk of mass m=2.00 x 10^-3 kg and radius R=2.20cm is attached at its center to a longfiber. When the disk is turned from the relaxed state through a small angle theta, the torque exertedby the fiber on the disk is proportional to theta. Find an expression for the torsional constant k interms of the moment of inertia I of the disk and the angular frequency w of small, free oscillations.The disk, when twisted and released, oscillates with a period T of 1.00 s. Find the torsional constantk of the fiber.

Given: The given values are, Mass, m=2.00×10-3kg Radius, R=2.20cmR=2.20×10-2m Period of time,…

Answered: A thin metal disk of mass m=2.00 x…

A 1.25 m long cable has a diameter 3.50 mm with a Young's Modulus, E, of 9.75 x 109 N/m2. When the wire is placed under tension, it experiences a stress of 202.52 x 106 N/m2, the length of the cable extends by 36.35 mm. Calculate the force that the cable experiences under tension and the strain energy density (UV) due to deformation. Give your answers in newtons (N) to 2 decimal places for the force; and in joules per cubic metre (J/m³) for the strain energy density to 2 decimal places. Assume the cable is solid and the material is homogeneous
1. A uniform bar has a small ball hanging at a distance x. The bar is 2.00 m long and has mass 4.00 kg, while the ball has a 3.00 kg mass. The Tension in the string is 100 N 37.0 Ar a) Find the Position “x" on the Rod where the ball is hanging b) Find the Force exerted by the Hinge (Point A) on the Rod After experimenting the bar showed to have a non uniform density that varies as P(x)=C(1+0.1x²) in the interval 0

During a dunk, a basketball player will elevate theircenter of mass 70 cm (or more) while jumping off of one leg. What is the strain energy contribution to the energy required to elevate the center of mass given the following parameters? How much energy has to be contributed by active muscle contraction? mass = 82 kg, K leg = 35000N/m, dispacement = 0.11 m.
I needed help with this question: It says to find the angular frequency in radians. I determined the amplitude to be 10 based on the graph but I am having trouble on how to caluclate the angular frequency. To my understanding I am supposed to use the formula: x(t)= Acos(wt+del) where w= angular frequency and del= phase constant
