The applied force

Answer to Problem 10TP
The applied force is around
Explanation of Solution
Given:
Number of bricks in the wheel barrow is
Mass of each brick is
Formula used:
Write the expression for force.
Here,
Write the expression for torque.
The mechanical
The torque due to the output force is equal n magnitude and opposite in direction o the torque caused by the weight. Thus,
Since, the mechanical advantage is the ratio of output force to input force. The ratio can be written as,
Conclusion:
Force due to wheelbarrow is calculated as,
Force due to the weight of
Total force due to the weight is calculated as,
The net torque s calculated as,
The output force is calculated as,
The input force is calculated as,
For an empty wheelbarrow the output force is,
The input force for an empty wheelbarrow is calculated as,
Conclusion:
Therefore, the applied force is around

(Let C = 12.0 µF.) A circuit consists of four capacitors. It begins at point a before the wire splits in two directions. On the upper split, there is a capacitor C followed by a 3.00 µF capacitor. On the lower split, there is a 6.00 µF capacitor. The two splits reconnect and are followed by a 20.0 µF capacitor, which is then followed by point b.

I have uploaded the picture of a video on YouTube. Thanks,arrow_forwardA spectra is a graph that has amplitude on the Y-axis and frequency on the X-axis. A harmonic spectra simply draws a vertical line at each frequency that a harmonic would be produced. The height of the line indicates the amplitude at which that harmonic would be produced. If the Fo of a sound is 125 Hz, please sketch a spectra (amplitude on the Y axis, frequency on the X axis) of the harmonic series up to the 4th harmonic. Include actual values on Y and X axis.arrow_forward
