Two forces, _1 and _2, of magnitude 10 and 30 pounds, respectively, act on an object. The direction of _1 is N20° E and the direction of _2 is N65° E. Find the magnitude and the direction of the resultant force. Express the magnitude to the nearest hundredth of a pound and ...
The magnitude of the resultant of two forces P and Q is equal to the magnitude of P. The magnitude of the resultant of 2P and Q is equal to √3 times the magnitude of P. Find the magnitude of Q and show that Q makes an angle of 120° with P....
This means that for any apparent contact angle value measured using an optically flat line, if the true microscopic contact angle could be somehow measured, it would be lower in magnitude. This should not be confused with our observations of the trend where the apparent water contact angle ...
5. A particle is acted upon by two forces F and G. The force F has magnitude 8N and actsin a direction with a bearing of 240°. The force G has magnitude 10N and acts due South.Given that R=F + G, find(i) the magnitude of R,(ii) the direction of R, giving your answer as...
there is no such thing as a repulsive gravitational force. Gravitational forces between any and all objects in the universe is always attractive. In vector form, attractive forces are always negative but for magnitude's sake, we can remove the negative sign. The magnitude ...

Infertility is a prominent problem affecting millions of couples worldwide. Recently, there has been a hightened emphasis on elucidating the subtle linkages between infertility treatment leveraging assisted reproductive technology and the complex realm o
Whereas the forces on the cylinders are equal in magnitude but of opposite sign, the torques are in general different. If only one of the cylinders has a vanishing loss angle a "uni-lateral" torque exists. In the case of identical cylinders the expressions for the interactions are essentially...
Influence of the Type of Contact between Particles Joined by a Liquid Bridge on the Capillary Cohesive Forces The influence of the particle dimensions and type of interparticle contact on the magnitude of the capillary forces between the powder particles is studied... Tselischev Yu.G,VA Valtsife...
, the oil film may be squeezed out from between them . This could result in flaking and spalling of the metal , noise , rough motion , and eventual failure . In the study of mechanics we are principally interested in determining the magnitude , direction , and location of the forces ....
