Explanation:
1. Circumference is pi times diameter.
C = πd
C = 9π inches
C ≈ 28.3 inches
2. Mechanical advantage is ratio of output force to input force.
MA = Fout / Fin
MA = 155 lb / 15 lb
MA ≈ 10.3
3. Mechanical advantage is ratio of input distance over output distance.
MA = din / dout
MA = 10.5 in / 0.85 in
MA ≈ 12.4
4. Mechanical advantage of pulley system is the number of strands.
MA = 8
5. Mechanical advantage is ratio of output force to input force.
MA = Fout / Fin
8 = Fout / 200 lb
Fout = 1600 lb
Answer:She will be selected by "Optimistic Unchoking".
Explanation:BitTorrent is a communication protocol for peer-to-peer file sharing (P2P) it is used to distribute data and electronic files over the Internet.
Optimistic unchoking is an important factor in BitTorrent peer-to-peer (P2P) file sharing networks, with optimistic unchocking there is always one peer that is unchocked.
BitTorrent Peers use optimistic unchoking to find the upload bandwidth details concerning other peers.
However, free users have been known to also make use of optimistic unchoking and download from the network without uploading anything.
Answer:
Time required for iron rod surface temperature to cool to 200°C is 250 seconds.
Explanation:
Answer:
1. Mechanically actuated
2. Electrically actuated
3.Pneumatically actuated
Explanation:
The general method of actuation of brakes are as follows:
1. Mechanically actuated
In this method linkages or livers are used to produce the action of brakes.In this mechanical component is used to apply the brakes. Band brakes,shoe brakes etc are the example of mechanical breaks.
2. Electrically actuated
In this method magnetic coil is used to and this magnetic coil produce magnetic field due to this magnetic filed brakes apply.
3.Pneumatically actuated
In this method compressed air is supply from high pressure vessel and this pressurized air apply the break.
Answer:
Temperature on the inside ofthe box
Explanation:
The power of the light bulb is the rate of heat conduction of the bulb,
The thickness of the wall, L = 1.2 cm = 0.012m
Length of the cube's side, x = 20cm = 0.2 m
The area of the cubical box, A = 6x²
A = 6 * 0.2² = 6 * 0.04
A = 0.24 m²
Temperature of the surrounding,
Temperature of the inside of the box,
Coefficient of thermal conductivity, k = 0.8 W/m-K
The formula for the rate of heat conduction is given by:
