Question

The solutions require supporting work and/or explanations; answers alone are not sufficient. These problems will be graded based on three factors:

Accurate strategy and analysis method used when solving the problem correctly.

Explanation of work, including using an equation editor where required. PLEASE SHOW WORK!!!

400 lb 200 lb A hoist trolley is subjected to the three forces shown. Knowing that a 40, determine (a) the required magnitude of the forcc P if the resultant of the thrcc forccs is to be vertical, (b) the corresponding magnitude of the resultant.

Explanation / Answer

a) Now let us balance horizintal forces

400 cos a -200 sin a - p

so now if resultant should be 0 then

p = 400 cos a - 200 sin a

b) Resultant is in downward direction

= 400 sin a + 200 cos a
