✅ The verified answer to this question is available below. Our community-reviewed solutions help you understand the material better.

A thin disk with radius r is supported by a spring of stiffness k. A trolley, with a mass of m subscript T, rests on a surface with a slope of alpha, and is attached to the disk at the same point as the spring. Assume that the disk has a mass of m and rolls without slipping. Also, assume that the trolley moves frictionlessly and that the trolley's wheels, as well as the pulley between the trolley and disk, are massless. Assume that g equals 9.81 space straight m divided by straight s squared.

The system parameter values are:

 m equals2.2 kgm subscript T equals2.8 kgk equals5.7 straight N divided by straight malpha equals0.364 rad and r equals0.8 straight m.

Calculate the static deflection of the disk, theta subscript 0, in radians.

 NB: Provide your answer to two (2) decimal places and do not use any units in your final answer. Example: 2.099145... [m] should be entered as "2.10".

 

'n Dun skyf met radius r  is deur 'n veer, met styfheid k, ondersteun. 'n Trollie, met massa m subscript T , wat op 'n oppervlakte met 'n helling van alpha staan is aan dieselfde punt op die skyf vasgemaak as die veer.  Aanvaar dat die skyf 'n massa van m het en oor die oppervlakte rol sonder glip.  Aanvaar ook dat die trollie  wrywingloos teen die oppervlakte beweeg en dat die trollie se wiele asook die katrol tussen die trollie en skyf massaloos is. Neem aan g equals 9.81 space straight m divided by straight s squared.

Die waardes van die parameters van die sisteem is:

 m equals2.2 kgm subscript T equals2.8 kgk equals5.7 straight N divided by straight malpha equals0.364 rad en r equals0.8 straight m.

Bereken die statiese defleksie van die skyf, theta subscript 0, in radiale.

LW: Gebruik twee (2) desimale in die finale antwoord. Moet nie eenhede gebruik in die antwoord nie. Voorbeeld: 2.099145... [m] moet as "2.10" ingeskryf word.
