    MathCAD query - Multiplication of an Array Varible

    Thanks for the responses all, in this case the recommendation provided by Stick seemed to do the trick nicely (i.e. to 'vectorise' the equation) and negated a lot of unnecessary duplication which was great. Next time I'll be sure to post to the correct forum though as i didn't realise there was...

    MathCAD query - Multiplication of an Array Varible

    Hi, I was hoping someone may be able to help me with an issue I am encountering using MathCAD Prime 9 relating to the use of arrays to solve an equation which contains a variable which has multiple values. To provide context, I am looking at analysing a simple beam with fixed ends with a...

    Assistance producing a FBD to assess forces on a restraint bolt

    The answer to your question is that is a project which involves the design of a carriage which is required to manoeuvre a heavy valve into a position which allows internal maintenance of the valve to be undertaken - arrgt shown below. The objective here was to simplify the set up and simulate...

    Assistance producing a FBD to assess forces on a restraint bolt

    Many thanks for this response. It occurred to me last night when rb1957 queried the presence of the gap, that the removal of this and replacement with a pivot, should simplify should the problem and your response confirms what I was thinking which is great. In terms of the loading on the bolt...

    Assistance producing a FBD to assess forces on a restraint bolt

    Sorry my mistake the 'upstand' is not connected to the horizontal section of the (continuous) 'L' piece which is free to pivot - the bolt provides the constraint to prevent this rotation. My statement above re. the connection being rigid is incorrect. Does this arrangement effect the above...

    Assistance producing a FBD to assess forces on a restraint bolt

    Hi, Thanks for the response. If I understand your response correctly (?) your logic is as follows: 1. The RHS side of the bolt (Point 'B') is contact with the grounded upstand post which imparts a normal (vertical) reaction force of F onto the bolts contact surface, equal and opposite to the...

    Assistance producing a FBD to assess forces on a restraint bolt

    Hi, apologies I just noticed that at the head of the bolt I have missed a reaction force to compensate for the force acting on the shank so the FBD should have looked like:

    Assistance producing a FBD to assess forces on a restraint bolt

    Hi, I was hoping somebody may be able to help me generate a FBD for the forces imparted onto bolt/pin located which is designed to prevent rotation of the simple structure shown in the image below https://www.eng-tips.com/threadminder.cfm?pid=1630 I am assuming that the bolt has moment arm...
