Lecture 16 (R 4.7)
Determine the force in each member.
All triangles are equilateral of dimension d
Notes
1. All angles are 60o
2. Find reactions
3. Joints A, B, E, D, C, G
3
Lecture 17 (4.27)
Find the force in member CG
Notes
1. Inclined members are at 45o
2. Find reactions at A and G
3. Pass imaginary section through GF, GC, BC
4. Analyze right section (don’t need reactions)
5. Analyze left section (need reactions)

Lecture 18 (4.66)
Determine the components of all forces
acting on each member of the loaded frame.
Lecture 19
Lecture 22(SP 5/12)
In this case the load varies in a more
complicated fashion. First, we need to
find the constants.
Lecture 24 (5/15)
Draw the shear-force and bending-moment diagrams
for the loaded beam and determine the maximum
moment M and its location x from the left end.
Lecture 25 (6.3)
Determine the magnitude and direction of the friction force acting
on the 100-kg block shown if, first, P = 500 N and, second, P = 100 N.
The coefficient of static friction is 0.20, and the coefficient
of kinetic friction is 0.17. The forces are applied with the block initially at rest.
