Concept explainers

Moment of Inertia

Inertia can be termed as a resistance offered by a body to change its state. A rigid body initially at rest will apply resistance when acted by an external force that tends to change its state of rest or velocity, or a body initially at motion will provide resistance in changing its state of velocity or motion for coming to a state of rest. In other words, Newton's first law of motion describes the law of inertia of a rigid body.

Figure shows two forces, one 500 N and the other P applied by cables on each side of the obstruction A in order to remove the spike. 5mm- P 8mm 450N Write a MATLAB program to determine: (a) the magnitude of P necessary to such that the resultant T is directed along the spike. (b) the magnitude of T. (c) plot P and T as a function of d. (Range of d between 1 and 20 mm). From equilibrium: 0= Psin a – 450 sin B EFx=0 T=P cos a + 450 cos B EFy=0 T Solving the above eqns; P = (450 sin B) / sin a T= 450 (sin ß cot a + cos B) P 450N FBD B Form geometry: 46 a =tan1 (5/d) and B =tan-1(8/d)

3) A point mass is attached to one end of a beam levered against a spike which acts as the pivot. The point mass weighs 250N and the beam has a uniform mass of 10kg and is 8m long. Parts a and b Part c Fapplied 3 of 6mov 1m 8m Krist 0 = 60° Scale 250 N Scale a. If a scale placed beneath the point mass reads 250N, what is the magnitude and direction for the force at the pivot point? Direction: North, 90° from x-axis Magnitude to k* 250N = 2500 N b. For the same scenario, how far must the pivot point be located relative to the left edge of the beam? (Hint, both the boxes weight and the force from the scale act at the farthest right edge of the beam.) www.acta 0672nos onl c. The pivot is then moved to be 6m from the left edge of the beam which now makes a 60 angle with the floor. How much downward force would be needed at the left-most edge of the beam to reduce the reading on the scale to zero? (Hint: the beam is still in static eq. when the scale reads zero.)
