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

A motorboat maintained a
constant speed of 15 miles per hour relative to the water in
going 10 miles upstream and then returning. The total time
for the trip was 1.5 hours. Use this information to find the
speed of the current.

Ans: 5 mi/hr.
Any solution for this? Thanks

Hi! Pahelp please? Anyone who has a good heart huhuhu. I badly need your help. Anyone who can answer this? I mean with the process.

The collar has a mass of 3kg and is supported on the rod having a coefficient of kinetic friction Uk=0.4. The attached spring has an unstretched length of 0.2m and stiffness k=50N/m. Determine the speed of the collar after the applied force F=200N causes it to be displaced s=1.5m from pt. A. When s=0 the collar is held at rest?

What is the process?
