The moment of inertia of a body about an axis is sometimes represented using the radius of gyration. Radius of gyration is the imaginary distance from the centroid at which the area of cross section is imagined to be focused at a point in order to obtain the same moment of inertia. It is denoted by k.

Revolution in 1 sec = 7/100=0.07sinverse Angular speed =2pie n=2*22/7*0.07=0.44rad s inverse. Linear speed = omega *r=0.44*0.12=0.0528ms inverse.

Priya Dharshini ☺☺ 7 years, 2 months ago

Let P and Q be two vectors acting simultaneously at a point and represented both in magnitude and direction by two adjacent sides OA and OD of a parallelogram OABD as shown in figure. Let θ be the angle between P and Q and R be the resultant vector. Then, according to parallelogram law of vector addition, diagonal OB represents the resultant of P and Q. So, we have R = P + Q Now, expand A to C and draw BC perpendicular to OC. From triangle OCB, In triangle ABC, Also, Magnitude of resultant: Substituting value of AC and BC in (i), we get

According to 1st law of motion :- "A body continue in the position of rest or the uniform motion along a straight line . unless external force act on it." According to 2nd law of motion :- " the rate of change of linear momentum is directly proportional to the applide force " According to 3rd law of motion :- "For every action there are equal nd opposite reaction . action nd reaction act on the diff.bodies" Hope it help u a lot☺☺☺☺☺☺☺
