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:
Move the buret clamp to a ring stand with a larger base.
Explanation:
A right stand is used for titration experiments in the laboratory. It holds the burette firmly during experiments so that accurate readings can be taken.
The right stand is made up of support base, vertical stainless steel, clamp with adjustable screw that holds on to the vertical rod.
The clamp is used to hold the burette in place.
If after clamping a buret to a ring stand, you notice that the set-up is tippy and unstable, the best action will be to move the buret clamp to a ring stand with a larger base.
The larger base provides a better center of gravity and stabilises the setup
Answer:
a) attached below
b) The worst case in tension is case ( 9-7 ) b which is
= -65k
The worst case in compression is case ( 9-5 ) a which is
= 670 k
Explanation:
Given data :
D = 150k , L = 280k , Lr = 40k , s = 50k , w = ± 120k
E = ± 200k
attached below is a detailed solution to the given problem ( problem 1 )
A) attached below
b) The worst case in tension is case ( 9-7 ) b which is
= -65k
The worst case in compression is case ( 9-5 ) a which is
= 670 k
Answer:
the final temperature would have been 2.81 °C if the pressure drop was 2 psi
Explanation:
if we assume that is no change in volume, there are not leaks present and also that the gas inside the football behaves as an ideal gas, we have:
initial state) P1 V = n R T1
final state) P2 V = n R T2
where P = absolute pressure , V = volume occupied by the gas, n = number of moles of gas, R = ideal gas constant T= absolute temperature
therefore since V= constant (constant volume) and n= constant ( no leaks), if we divide both equations
P2/P1 = T2/T1
therefore
T2 = T1 *(P2/P1)
since P1 absolute = P1 relative + P atmospheric (14.7 psi) = 12.5 psi + 14.7 psi = 27.2 psia
also P2 = P1 - 2 psi = 25.2 psia
T1 = 24.7°C + 273 °C = 297.7 K
therefore
T2 = T1 * (P2/P1) = 297.7 K ( 25.2 psia/27.2 psia) = 275.81 K
thus T2 = 275.81 K = 2.81 °C
