Ahh right, so only only if you had torques exerted on both links would the mass be sustained by both?
Yeah I usually would have done those as dotted lines to show they are resultant forces, i drew that very quickly. Your pedantism has been very helpful /s
Yes:
$$\textbf{I'm just confused as to why there is no vertical component of the force at D}$$
Why's that?
I would have thought it would be equally distributed? What about tangential acceleration? Why would this not be felt at both B and D?
Cheers
The fluid is static. ie. in equilibrium. Remember that you can think of pressure at a point as being exerted equally onto that point from all directions. So if the pressures were different at the bottom on the left and right, then there would be a net flow from high pressure to low pressure ie...
If I'm not mistaken:
Yes, it's because the tank is sealed. The water is at different heights so the pressure differential is given by:
$$\rho_A g h_1 - \rho_w g h_2 - \rho_B g h_3 \\ = g(2\rho_A - 2\rho_w) \\ = 2g(\rho_A-\rho_w)$$
assuming ##\rho_A = \rho_B##
its been a while since I've done...
Homework Statement
Viewing a solution on the internet to this question, the free body diagram is drawn as:
The forces here are then used to solve for ##F_D## and this is given as the answer to "the force which the bar exerts on the link at D". I'm just confused as to why there is no...
If a body is moving in one constant direction, is it considered stationary with respect to other directions? For example, consider a table. Let the surface of the table be defined by an x-y Cartesian plane. If the body is moving in the x direction on the table, and a force (< (μs * Fn)) is...
Yes. I think I have the solution:
ΣFy = ΣρQ(outlet) (because V1y = 0, inlet term of momentum equation is zero)
for mass flow rate at outlet we only need to consider outlet 2 because velocity y-component of 3 is also zero. The mass flow rate at 2 is 2 kg/s and V2 = 1 so we have:
ΣFy...
Homework Statement
A water jet hits a wall and splits into two streams (see attachment). The jet carries 3kg of water per second. The cross-sectional area of the flow at (2) is A = 2*10^-3 m^2. The average velocities at the outlets are V2 = V3 = 1m/s
What is the net vertical force exerted by...
