I want to do some math for 4-link suspension, and I soon realized I don't know crap. Say I take measurements of the lengths of the four connecting rods and one angle measurement. How do I find the values of the other three angles?
A slender rod of length l and mass m rotates with constant angular verlocity omega about an axis which is at an angle alpha to the rod and pases through its centre. Obtain an expression for the torque acting on the rod and get eth equation of motion of the rod once it is released from its...
Two identical uniform beams, each having a mass of 4 kg, are symmetrically set up against each other on a floor with which they have a coefficient of static friction µ = 0.609 .
a) What is the minimum angle the beams can make with the floor without falling?
b) For the angle calculated in...
The rear-view mirror of a car is so placed that its upper and lower edges are horizontal and its cener is at the same level as the center of the rear window. The driver's eye is also at this level, and the line of sight from his eye on the center of the mirror makes an angle of 30 degrees with...
HELP please: vector angles and velocity
Alright i don't nessesarily need an answer for this but maybe just a way to set it up. The problem is worded weird and no one can figure it out.
A passenger walks from one side of the ferry to the other side as it approaches a dock. If the...
I understand that Sin is Opposite over the Hypotenuse, Cosine is Adjacent over Hypotenue, and Tangent is Opposite over the Adjacent. But I don't know how to use it. Sin has its own equation, as does Tangent...I am just confused. What do I do to find a specific angle? What about a certain side...
Why does a circles angles equal up to 2pi? Wouldn't it be 1pi? Please help.
My geometry teacher (last year - and now he's gone) drew a circle for me and defined all the points in terms of pi (is there an ASCII character for pi, by-the-way, on the keyboard?). Where the 90 degree point would be...
ok so this was in my end of unit test today and i have been stressing as to what i should have done, so as it's not really homework you could always just tell me the answer
pretty basic stuff, a ray of light is incident from a substance upon the surface of another substance with n=1. i...
An enemy ship is on the western side of a mountain island. The enemy ship can maneuver to within 2500 m of the 1800-m-high mountain peak and can shoot projectiles with an initial speed of 250m/s. If the eastern shoreline is horizontally 300m from the peak, what are the distances from the...
