Sorry a negative number means it is compression and a positive number means it is in tension.

Thanks very much! One last thing. I am now finding the forces in Members FC and FG. Am I right in saying: Forces in direction: -(-4000) - FC x sin(53.1) = 0 and then I just rearrange for FC = 5000 Newtons and now I know FC I can do the following: Force in direction: 0 + (FC x cos(53.1)) +...

Homework Statement a) Find the reactions provided by the foundations at A and B. b) Use the method of Resolution at the Joints to calculate the forces in all the members. c) Which member will fail first and why ? Homework Equations ƩFx = 0 ƩFy = 0 ƩM = 0 The Attempt at a...

I am doing a bit of self study and background reading and was wondering if anyone could explain what the Constant is in Boyles Law and in the constant in the Combined Gas Law? Following on from that, what is the significance of the Constant? Does air have a particular constant for Boyles Law and...

Homework Statement A simple pendulum consists of a spherical bob of mass 0.052 kg and diameter 1.1 cm attached to a thread of length 920 mm. b) The bob is released at rest with the thread taut at an angle of 5 degrees to the vertical. Calculate: i) the amplitude of the oscillation...

The bobs Max Velocity will be when it is mid-way between it's maximum displacement. This is also it's point of minimum velocity. But I am still stumped. Sorry.

Homework Statement A simple pendulum is observed to perform 40 oscillations, of amplitude 40 in 100 seconds. Find: i) the length of the pendulum ii) the maximum angular velocity of the pendulum bob iii) the maximum angular acceleration of the bob The Attempt at a Solution i)...

I need to obtain the mass per unit length. Is it as simple as just mass / length?
