In line S.H.M what can you say about the restoring force when the speed of the particle is maximum |
|
Answer» The RESTORING force is the force that brings the object back to its equilibrium position; the minus sign is there because the restoring force acts in the direction OPPOSITE to the displacement. ... In the absence of force, the object WOULD REST at its equilibrium position. |

Considering the stress element for the outermost layer of the shaft (question 3) at point A (figure 3), draw the Mohr’s circle for the same. From the analysis of Mohr’s circle, find the principal stresses and the position of principal planes. Also draw the stress element for principal stresses along with its orientation in reference to the stress element found in |
|
Answer» Answer: Explanation: Introduction • The transformation equations for plane stress can be represented in graphical form by a plot known as MOHR’s Circle. • This graphical representation is extremely useful because it enables you to VISUALIZE the relationships between the normal and shear stresses ACTING on various inclined planes at a point in a stressed body. • Using Mohr’s Circle you can also calculate principal stresses, MAXIMUM shear stresses and stresses on inclined planes |

Force produces an acceleration of 3.0 ms-2in a body P and 10ms-2in another body Q. Find the ratio of the mass of P to the mass of Q........ Pls tell fast and explain briefly |
|
Answer» <P>Answer: 10:3 Explanation: Let the force experienced by P and Q be F1 and F2 respectively and the MASS of P and Q BT M1 and M2. Given F1=M1×3...(1) and F2=M2×10...(2) now according to the QUESTION F1 and F2 are equal. dividing 1 and 2 we get M1/M2=10/3 therefore the required ratio M1:M2=10:3 |

An iron anchor has a density of 480kg/m³ and weighs 250kg in air. If it is immersed in a sea water that has a density of 64kg/m³,how much force would be required to lift it while it is immersed? |
|
Answer» Answer: If you WANTED to immerse the anchor, you WOULD have to apply a downward force of 817.5 N to fully immerse this “anchor” completely under the water. This anchor has a mass of 250 kg. Therefore, it's WEIGHT is: W=mg=(250KG)(9.81ms2)=2452.5N downward. |
