Amiraneli [1.4K]

Answer:

100N
25N

Explanation:

a) On the verge of tipping over, reaction acts at the corner A

When slippage occurs,

Block moves w/ const. velocity  equilibrium

Three-force member: reaction at A must pass through B

tan b/2h, h b/ 2 θ µ = = ∴= k k ( µ )

b) When slippage occurs,

Block moves w/ const. velocity  equilibrium

Three-force member: reaction at C must pass through G

k tanθ µ =

tan x/ H/2 , x H/2

A gas cylinder is connected to a manometer that contains water. The other end of the manometer is open to the atmosphere, which

horrorfan [7]

Answer: the absolute static pressure in the gas cylinder is 82.23596 kPa

Explanation:

Given that;

patm = 79 kPa, h = 13 in of H₂O,

A sketch of the problem is uploaded along this answer.

Now

pA = patm + 13 in of H₂O ( h × density × g )

pA= 79 + (13 × 0.0254 × 9.8 × 1000/1000)

pA = 82.23596 kPa

the absolute static pressure in the gas cylinder is 82.23596 kPa

The motor of an electric vehicle runs at an average of 50 hp for one hour and 25 minutes. Determine the total energy. Write the

Sunny_sXe [5.5K]

Answer:

The total energy of the motor of the electric vehicle is 1.902 × 10⁸ joules.

Explanation:

Power is the rate of change of work in time, since given input is average power, the total energy ( $\Delta E$ ) of the motor of the electric vehicle, measured in joules, is determined by this formula:

$\Delta E = \dot W \cdot \Delta t$

Where:

$\dot W$ - Average power, measured in watts.

$\Delta t$ - Time, measured in seconds.

Now, let convert average power and time into watts and seconds, respectively:

Average Power

$\dot W = (50\,hp)\times \frac{746\,W}{1\,hp}$

$\dot W = 3.730\times 10^{4}\,W$

Time

$\Delta t = (1\,h)\times \frac{3600\,s}{1\,h} + (25\,min)\times \frac{60\,s}{1\,min}$

$\Delta t = 5.100\times 10^{3}\,s$

Then, the total energy is:

$\Delta E = (3.730\times 10^{4}\,W)\cdot (5.100\times 10^{3}\,s)$

$\Delta E = 1.902\times 10^{8}\,J$

The total energy of the motor of the electric vehicle is 1.902 × 10⁸ joules.
