we see the world‚ that is we need to understand that all problems are simply fragments of one single crisis‚ the crisis of perception. We need to change our system. The system thinks about intervention and not about prevention. Our world lacks vision‚ perspective‚ interconnectedness and relationships. We need to improve our education system. We need to understand that we are the one’s responsible for our acts if no matter if we are involved directly or indirectly in the consequence of our actions

the average and rms values of the periodic voltage or current waveforms‚ are computed? Some examples are also described there. In this lesson‚ the representation of sinusoidal (ac) voltage/current signals by a phasor is first explained. The polar/Cartesian (rectangular) form of phasor‚ as complex quantity‚ is described. Lastly‚ the algebra‚ involving the phasors (voltage/current)‚ is presented. Different mathematical operations – addition/subtraction and multiplication/division‚ on two or more phasors

the acceleration due to gravity‚ g is always vertically downwards and hence has no effect on the horizontal motion of the projectile.Thus projectile motion is two-dimensional motion.We can consider the plane of plane of motion as the x- coordinate and y- coordinate with the x-axis horizontal and the y-axis vertically upward. In another words‚ projectile motion can be resolved into two perpendicular component: a horizontal component with constant velocity (zero acceleration)and a vertical

bending of two unsymmetrical section cantilevers: 1. An equal angle with one axis of symmetry. 2. A Z section completely unsymmetrical. Apparatus: Vertical cantilever system‚ dial gauges‚ standard weight‚ hanger‚ cantilever beams of L and Z section. Procedure: 1. Mount up a beam section on the vertical cantilever system and measure the cross sectional dimensions. 2. Set the position of a geometrical axis of the beam section at zero degree. 3. Start the bending test on the cantilever

the screen make sure that you don’t draw outside the screen. This can be very fast‚ but increases the complexity of the triangle-filler (and it’s not as easy as 3D-clipping can be). This clipping method works directly with two-dimensional screen-coordinates. In 3D clipping you do everything in 3D space. (In my examples it’s done in camera-space. If you don’t know about this don’t worry about it.) If we want to clip in 3D space we need to have a description of the stuff the camera of our rendering-engine
