i have attached the working in the picture uploaded above

can you show me where is the r for the FB to generate restoring moment and overturning moment in the diagram ? so that i can understand better what you said

i have redo the question , i got Acos2x + Bsin2x +0.25x^2 + 3/2 , but the ans given is Acos2x + Bsin2x +0.25x^2 +3/8

then , what is the correct yp ? i choose my initial yp = cX^2 + Dx + E , nut i found that the term E is similar to the A , so i multiply the initial yp with x , to get my new yp

Homework Statement i gt stucked here ... how to continue ? what's wrong with my working ? i found 2 values for D , whcih is wrong Homework EquationsThe Attempt at a Solution

Homework Statement when the ship is tilted more , the ship will become inclined more ( bigger portion of right hand side part of the ship will be submerged in water ) . this caused the center of buoyancy to be located more to the right , this cause the B is very far from the G . The ship will...

Homework Statement why the floating body still stable when G ( center of gravity ) is above the B ( center of buoyancy)? Homework EquationsThe Attempt at a Solution in my opinion , the statement is worng , because when G is above B , G has the tendency to move downward , causing the object to...

isnt that the the resultant force on blade and forecs of steam of water are of same magnitude and same direction ?

the horizontal component of force should be -1.272 N + 2.54 = 1.27N N to the right, whereas the direction and magnitude of vertical force is the same ? then , the direction of resultant of force should be upwards just like the diagram below?

z represent the difference in height between 2 points

do u mean since the width is unknown and constant through out the whole object , so we can take it out and leave the ans (Fx) is Force per unit width>

how to relate it to the P1 ? why not P1 = P2 , which is ρg(h1 +h2 +h3) ?

ok , i can understand the red part of the equation (9810)(2.1)(4.2)- 9810(0.35)(0.7) -Fx = 1000(5.88)(8.4-1.401) , but 1000(5.88)(8.4-1.401) is force , am i right ? it's not force per unit width... they are not having the same unit...how cvan they be equqal to each other?

Homework Statement why the resultant force on blade is acted downwards (toward A)? why shouldn't it be slanted upwards ? since the horizontal component of the force acted 2.12kN to the left , and 0.735kN upwards , we would get the resultant force acting slanted upwards , right ? Homework...

it should be P/ y + z + (v^2) /.2g , where v = velocity , y = ρg
