Hi, colleagues! Am preparing for CSWP-simulation exam. Have some problems with sample exam. My first problem: Manual Calculation 1.
The right answer is 7.354 lbs. But what is the process of calculation in details, please?
1. Reaction force on R is :
Sin(45)*10= 7.071lbs
2. the Moment is :
7.071*0.5 =3.53 lb.in
F on Y : (-F.cos45)+R+B=0.
M on Y : (F.cos45)*0.5)+(0.7*B) = 0
B = 5.05 (the other side of the bar oppiste to R).
Ry = 2.021
Reaction on R = sqrt(2.021^2 + 7.071^2) = 7.354
1. Reaction force on R is :
Sin(45)*10= 7.071lbs
2. the Moment is :
7.071*0.5 =3.53 lb.in
