WebFour rods A, B, C and D of the same length and material but of different radii r,r2,r3 and 2r, respectively, are held between two rigid walls. The temperature of all rods is increased through the same range. If the rods do not bend, then This question has multiple correct options A the stress in the rods A, B, C and D is in the ratio 1:2:3:4 B WebFor example, the rotational inertia of a solid cylinder with radius r r rotated about a central axis is I = \frac {1} {2}m r^2 I = 21mr2 and for a hollow cylinder with inner and outer radii r_i ri and r_o ro respectively, I = \frac {m (r_i^2 + r_o^2)} {2} I = 2m(ri2+ro2) Expressions for other simple shapes are shown in Figure 4.
WebJan 24, 2024 · Given Four rods of same material but different radii r and length l are used to connect two reservoirs of heat at different temperatures the one which will conduct most heat is. Here the rate of heat transfer r^2 is directly proportional to 1 / l So q / t ∝ r^2 / l. So dq / dt is directly proportional to r / l http://content.njctl.org/courses/science/ap-physics-1/rotational-motion/rotational-motion-multiple-choice-2/rotational-motion-multiple-choice-2-2015-01-13.pdf
WebSep 12, 2024 · The resistivity of a material is a measure of how strongly a material opposes the flow of electrical current. The symbol for resistivity is the lowercase Greek letter rho, ρ, and resistivity is the reciprocal of electrical conductivity: ρ = 1 σ. The unit of resistivity in SI units is the ohm-meter (Ω ⋅ m.
