A pin-connected frame is loaded, as shown. Calculate the pin reactions at A, B, and C. Neglect the weights of the members.

Determine the force the pins at A and B exert on the two-member frame shown.

1) Use the method of PINS to determine the true magnitude and direction of the forces in all the members of the truss shown below in Fig 3.1. A 60° 500lbs 8' B M 8' D C wwww

The figure shows a roof truss and the detail of the connection at joint B. Members BC and BE are angle sections with the thickness shown in the figure. The working stresses are 70MPa for shear in the rivets and 140MPa for bearing stress due to the rivets. How many 22mm diameter rivets are required to fasten the following members to the gusset plate: (a) BC; and (b) BE? 000 4 m B с 96 kN D 6 m E 200 KN 4 m F G 4 m 96 kN H to- PBC - -14-mm-thick gusset plate -13-mm-thick angle 6-mm-thick angle PBE

Why do you integrate y instead of A? And why it’s it between 2a-a rather than 2a-0

please answer do not image format

The homogenous material wire ABCD is bent as shown and is attached to a hinge at C. Determine the length L in mm in which portion BCD of the wire is horizontal in position. Determine the length L in mm in which portion AB of the wire is horizontal in position (meaning portion BCD is inclined) -80 mm- B IC 60 mm

Please show complete solution. Thank you!

The support at "C" looks like a pinned connection to me. Therefore I believe the degree of indeterminacy goes up to two and it changes up the question quite a bit. Am I mistaken?

B 6m LP P -8m- -8m- -8m -8m In the bridge truss shown in figure, the end chord AB is composed of two C 230 x 30 channels latticed together so that the fabricated section has equal moments of inertia about the axes of symmetry. Properties of C 230 x 30 Ix = 25.5 x 10^6 mm^4 A=3800 mm^2 %3D a. Determine the slenderness ration of section AB. b. Determine the capacity of member AB. c. If the safe load P on the truss is governed by the strength of member AB, which of the following gives the value of P using NSCP Specifications with Fy = 290 MPa. %3D
