    Calculating Force on Quarter Cylinder Dam Gate with Hinge and Stopper

    Thanks, I spoke to the lecturer today and he said that the reaction from the ground is zero.

    Calculating Force on Quarter Cylinder Dam Gate with Hinge and Stopper

    Alternatively am I thinking about this problem in the wrong way and need to try a different method to find the force on the stopper?

    Calculating Force on Quarter Cylinder Dam Gate with Hinge and Stopper

    This is a picture of a quarter cylinder dam gate with a hinge at A and a stopper at B. I need to find the force on the stopper at B as a function of the radius (R) and height of the water (h). I was going to do this by working out the moments around the hinge at A. I can solve for pressure...

    Why Does My Pendulum Pin Support Reaction Calculation Differ from 299N?

    I've got a similar question to http://www.chegg.com/homework-help/questions-and-answers/pendulum-consists-10-kg-uniform-slender-rod-15-kg-sphere-pendulum-subjected-torque-m-50-n--q2722886 for homework. I applied the same steps I used on my homework question to this problem and I get a different...

    Angular momentum or work-energy balance?

    The apparatus above has an initial angular velocity of \omega_{1} as the rods are released. I need to find the angular velocity \omega_{2} of the apparatus at the bottom. I've tried 3 methods. First I tried a work-energy balance where I included a gravitational potential energy. KE_{1} + PE =...

    Engineering Straight Mechanical Engineering vs Dual Majors

    I'm currently studying a BEng (Mechanical) and was wondering about dual major options at my university. The two other majors that I'm looking at are Mechanical and Aerospace, and Mechatronic. I'm also considering doing a Masters of in either Electrical Engineering, Electricity Market or Systems...

    Double integral new coordinate system calculation

    Sorry, the lower bound on y for the first part should have been 1-x but I should be able to work through the rest of the reply and get an answer. Thank you for the detailed reply.

    Double integral new coordinate system calculation

    Homework Statement This is a 2 part question. I'm fine with the first part but the 2nd part I'm struggling with. The first part asks us to calculate the double integral, \int\intDx2dA for, D = {(x,y)|0≤ x ≤1, x≤ y ≤1} For this part I got an answer of 1/4. For the 2nd part we introduce a new...

    Understanding Fixed Support in Statically Indeterminate Problems

    Thanks all but I've got an answer to this. dv/dx = 0 is right.

    Understanding Fixed Support in Statically Indeterminate Problems

    I've just started to learn about how to solve statically indeterminate problems and I just want to check my understanding. If I've got a fixed support at x=0 then does that mean \frac{dv}{dx}=0, where x is distance along beam and v is deflection? As in the picture here,

    IVP ODE checking specifics of solution

    Homework Statement I've got an IVP where, 3xy+y2+(x2+xy)y'=0, y(1)=0 The Attempt at a Solution I've solved to get, x2y(x+\frac{1}{2}y)=0 Is it correct to say, x=0 or y=0 or y=-2x, Since y= 0 is the only solution that fits y(1)=0, then y=0 \forallx
