- The 4 kg disk D is attached to the end of a cord as shown in t
If the platform is rotating rapidly and the disk is placed on it and released from rest as shown, determine the time (in seconds), it takes for the disk to reach a speed great enough to break the cord The maximum tension the cord can sustain is 100N and the coefficient of kinetic friction between the disk and the platform is μk =0 1
- A uniform disc with mass M=4 kg and radius R= 10 cm is . . . - Tardigrade
A uniform disc with mass M=4 kg and radius R= 10 cm is mounted on a fixed horizontal axle as shown in figure A block with mass m =2 kg hangs from a massless cord that is wrapped around the rim of the disc During the fall of the block, the cord does not slip and there is no friction at the axle The tension in the cord is N (Take g =10 ms -2 )
- Circular motion and friction - Physics Stack Exchange
The maximum tension the cord can sustain is 100 N And the coefficient of the kinetic friction between the disk and the platform is 0 1 when the free body diagram of the particle was drawn, the friction force was considered in the tangential direction,, but it wasn't considered in the normal direction (tension was only considered)why?
- Dynamics Homework Problems: Rotational Motion Impact
Engineering mechanics homework problems covering rotational motion, angular acceleration, tension, friction, and impact College level
- The 3-kg disk d is attached to the end of a cord as shown in . . . - Brainly
We know that the maximum tension the cord can sustain is 100 N, so: 100 - mg - f_k = ma Solving for a: a = (100 - mg - f_k) m The final kinetic energy of the disk is then: K_f = (1 2)mv^2 where v is the final speed of the disk just before the cord breaks
- Coefficient of Friction Equation and Table Chart - Engineers Edge
N = m g Where: m = Mass (kg, slugs ) g = Gravity (9 81 m s 2 , 32 ft s 2) Static friction is friction between two or more solid objects that are not moving relative to each other For example, static friction can prevent an object from sliding down a sloped surface
- Friction - Coefficients for Common Materials and Surfaces
Find friction coefficients for various material combinations, including static and kinetic friction values Useful for engineering, physics, and mechanical design applications
