Rank in order, from smallest to largest, the six torques (torque 1 to torque 2) about the hinge.?

Physics
1 answer:
anzhelika [568]4 years ago
5 0
The solution for this problem is:torque1 = torque2 = FL / 2 
Torque 3 = Torque 4 = FL / 2 * sin (theta) 
Torque 5 = 2 FL 
Torque 6 = 0 

So the order of the torques from smallest to largest is torque 6, (torque 3 and 4), (torque 1 and 2), torque 5.


Remember or just take note that sin (theta) < 1 is why 3 and 4 are less than 1 and 2.

An undamped oscillator has period ro= 1.000 s, but I now add a little damping so that its period changes to r i= 1.001 s.
Firlakuza [10]

This Question has mistakes.Correct question is

An undamped oscillator has period  τo=1.000s , but I now add a little damping so that its period changes to  τ1=1.001s.

What is the damping factor β? By what factor will the amplitude of oscillation decrease after 10 cycles? Which effect of damping would be more noticeable, the change of period or the decrease of the amplitude?

Answer:

β=0.28 /sec

Amplitude=0.0606

Explanation:

T_{o}=2\pi  /w\\T_{1}=2\pi /\sqrt{w^{2} -\beta^{2}  }\\ As\\T_{o}=1 \\T_{1}=1.001\\From  T_{o}\\w=2\pi \\So\\T_{1}=w/\sqrt{w^{2} -\beta^{2}  }\\\beta =0.00447w\\\beta =0.00447(2\pi )\\\beta =0.28sec^{-1}\\ Amplitude=Ae^{-\beta t}\\ after\\ t=10T_{1}\\so\\Ae^{-\beta(10t_{1}) }=e^{-\beta(10t_{1}) }\\=e^{-\(0.28)(10)(1.001) }\\Amplitude=0.0606

A. assuming a perpetual inventory system and using the weighted average method, determine the weighted average unit cost after t
Monica [59]

Assuming a perpetual inventory system and using the weighted average method, the weighted average unit is determined as $11.44 after the October 22 purchase.

<h3>What is Weighted Average Cost (WAC)?</h3>

The Weighted Average Cost (WAC) method of inventory valuation in accounting uses a weighted average to establish the COGS and inventory levels.

The price of the products up for grabs is divided by the quantity of them in the weighted average cost technique.

The WAC technique is appropriate under both GAAP and IFRS accounting. Weighted Average Cost (WAC) Method Formula

<h3>Weighted Average Cost</h3>

Weighted Average Unit Costs = [360 units×$12 + (320-180) ×$10] / [360+(320-180)]units}

Weighted Average Unit Costs = $5720 / 500 units

Weighted Average Unit Costs = $11.44

Costs of goods that are offered for sale are calculated using beginning inventory value plus acquisitions.

Units available for sale are the number of units that can be sold by a company or the total number of units that are in its inventory.

The x component of vector is 8.7 units, and its y component is -6.5 units. The magnitude of is closest to
irina1246 [14]

Answer:

F = 10.86 units

Explanation:

The magnitude of a vector in terms of the magnitude of its rectangular components is given by the following formula:

F = √(Fₓ² + Fy²)

where,

F = Magnitude of the Vector = ?

Fₓ = magnitude of the x-component of vector = 8.7 units

Fy = magnitude of y component of vector = - 6.5 units

Therefore, using these values in the equation, we get:

F = √[(8.7 units)² + (- 6.5 units)²]

F = √(117.94 units²)

<u>F = 10.86 units</u>
