A hydraulic shear applies a 2000 lb force to a wedge. It is used to shear plate steel to rough size. The shear has a inch thick cutting blade with a 45 degree slope. (Note 45 , 45 , 90 triangle) 23. Sketch and annotate the wedge described above.

The nodal displacement vector {X} of the plane frame shown in the figure is given below. Evaluate the member end forces and moments of element # 11 in its local axis system and draw its bending moment, shear force and axial force diagrams taking E = 200 GPa, A = 500 mm2 and I = 250(106) mm4 for...

Studies have shown that the traffic flow on a two-lane (two-way) road adjacent to a school can be described by the Greenshields model. A length of 0.5 mi adjacent to a school is described as a school zone (See the figure below, a modified version of Figure 6.15). The school zone operates for...

Question 10. Current in an electric circuit is described by the differential equation LdI + RI = E , dt where L, R and E are positive constants. At the moment t = 0 there is no current: I = 0. Solve the differential equation to find I(t) in terms of the constants and sketch the solution...
