A 40 lb box is suspended from two ropes which each make an angle of 45 degrees with the vertical. What is the tension (in pounds

givi [52]

Answer:

The tension on each rope is 28.28 lb

Explanation:

Given that,

Weight = 40 lb

Angle = 45°

We need to calculate the tension on each rope

Considering the symmetry of the system, the tension of each rope must be same

So,

$T\sin\theta+T\sin\theta=mg$

Put the value into the formula

$2T\sin\theta=mg$

$T\times\sin45=\dfrac{40}{2}$

$T=\dfrac{40\sqrt{2}}{2}$

$T=28.28\ lb$

Hence, The tension on each rope is 28.28 lb.

Engine cylinder has an area of 0.01 m2. The gas exerts a constant pressure of 7.5 * 105 Pa on the piston and moves the piston to

kiruha [24]

Answer:

The positive sign indicates that work is done by the gas.

Explanation:

Let consider that gas inside the cylinder behaves ideally and process is isothermal, so that change in internal energy can be neglected. The engine cylinder is modelled after the First Law of Thermodynamics:

$W + P\cdot(V_{in}-V_{out}) = 0$

$W = P\cdot (V_{out}-V_{in})$

$W = P\cdot A\cdot \Delta x$

$W = (7.5\times 10^{5}\,Pa)\cdot (0.01\,m^{2})\cdot (0.04\,m)$

$W = 300\,kPa$

The positive sign indicates that work is done by the gas.
