Why dont some vehicles have power steering

Answer:

Because older cars didn't really have much power steering, and parking or even turning at low speeds could require a lot of strength to move the steering wheel on a big, heavy car. This moves the rack to the right or left, which turns the vehicle's wheels. Without power assist, you'd need grunt force to turn the pinion and move the rack.

Steam at 1400 kPa and 350°C [state 1] enters a turbine through a pipe that is 8 cm in diameter, at a mass flow rate of 0.1 kg⋅s−

sergeinik [125]

Answer:

Power output, $P_{out} = 178.56 kW$

Given:

Pressure of steam, P = 1400 kPa

Temperature of steam, $T = 350^{\circ}C$

Diameter of pipe, d = 8 cm = 0.08 m

Mass flow rate, $\dot{m} = 0.1 kg.s^{- 1}$

Diameter of exhaust pipe, $d_{h} = 15 cm = 0.15 m$

Pressure at exhaust, P' = 50 kPa

temperature, T' = $100^{\circ}C$

Solution:

Now, calculation of the velocity of fluid at state 1 inlet:

$\dot{m} = \frac{Av_{i}}{V_{1}}$

$0.1 = \frac{\frac{\pi d^{2}}{4}v_{i}}{0.2004}$

$0.1 = \frac{\frac{\pi 0.08^{2}}{4}v_{i}}{0.2004}$

$v_{i} = 3.986 m/s$

Now, eqn for compressible fluid:

$\rho_{1}v_{i}A_{1} = \rho_{2}v_{e}A_{2}$

Now,

$\frac{A_{1}v_{i}}{V_{1}} = \frac{A_{2}v_{e}}{V_{2}}$

$\frac{\frac{\pi d_{i}^{2}}{4}v_{i}}{V_{1}} = \frac{\frac{\pi d_{e}^{2}}{4}v_{e}}{V_{2}}$

$\frac{\frac{\pi \times 0.08^{2}}{4}\times 3.986}{0.2004} = \frac{\frac{\pi 0.15^{2}}{4}v_{e}}{3.418}$

$v_{e} = 19.33 m/s$

Now, the power output can be calculated from the energy balance eqn:

$P_{out} = -\dot{m}W_{s}$

$P_{out} = -\dot{m}(H_{2} - H_{1}) + \frac{v_{e}^{2} - v_{i}^{2}}{2}$

$P_{out} = - 0.1(3.4181 - 0.2004) + \frac{19.33^{2} - 3.986^{2}}{2} = 178.56 kW$

Researcher Timothy Salthouse suggests that if people are mentally active all of their lives, they enter late adulthood with ____

mylen [45]

Answer:

Researcher Timothy Salthouse proposes that if the person is mentally active throughout their lives, they will have a cognitive reserve in late adulthood that will help them continue to execute a high mental level.

Explanation:

The psychologist Timothy Salthouse focused his research on cognitive aging, and his study is considered very important in the area since it helped identify the first signs of cognitive impairment.

The psychologist Salthouse considered that if the person had an excellent cognitive reserve would not be strongly affected by the brain deterioration that occurs over the years.

The cognitive reserve is the competition that the brain has to balance the deterioration that occurs over the years in people. This cognitive reserve is related to the actions that the brain performed previously, habits, and knowledge acquired by the person over time.

Therefore, older adults who have taken actions to strengthen their cognitive processing will have better advantages in obtaining the cognitive reserve.
