Mga idol. Pwede pa turo pano to? Thanks in advance.

Problem 1

For a truss loaded as show, choose the lightest 2-angle sections to safely carry the maximum stress. The yielding stress of steel is 240 MPa. Use allowable compressive stress of 0.45 of the yielding stress and allowable tensile stress of 0.60 of the yielding stress. Assume that provision for buckling is provided.
F1 = 15 KN; F2 = 14 KN

2xy' + y³ e^(-2x) = 2xy

a soccer ball with mass 0.420 kg is initially moving with speed 2.00 m/s. a soccer player kicks the ball, exerting a constant force of magnitude 40.0 N in the same direction as the ball's motion. over what distance must the player's foot be in contact with the ball to increase the ball's speed to 6.00 m/s?

Find each member. (method of sections)

Geometrical Application

Find the eq. of the curve such that the x-intercept of the tangent line at any pt. (x, y) on it divided by the square of the ordinate is a constant.

Hello,

I'm writing because I have a problem that I don't know how to solve.
I would be thankul if someone could help me solve this problem.

The problem is as follows:

xy' = y + 2 √xy
