What i have worked out : 85th speed exceeds the limit by 24% = 37.mph. travels at 16.63 m/s average driver reaction time 1.5 seconds 16.63 x 9 = 149.67 m/s x 1.5 = 224.5 am i on the right wave lengths here, thanks for any help

Could you show me how you work this out then please

Firstly thanks for your help. I have 1025 as my mass. 9.81gravity. 4m difference in height. PE=mgh. This is what we had I'm class: 1025x2x2x9.81/6x60x60 200x10 to the power of 6. Slightly confused how they got this. Please could you help work through

What I have worked out: ep=mgh P2hgh/6x60x60 1025x2x2x9.81x2/ 6x60x60 =745gw

A tidal barrage contains an area of of sea of 200km2 and the tidal range 6m at spring tides and 2m at neap tides. What would be the average power output over the year? Any help would be great,

Hi I am starting as a highway engineer. My work college has given me this to try any help woul dbe great. A pedestrian requires to cross a two-way carriageway which is 9 metres wide to access a railway station. Given that the road is subject to a 30mph speed limit, wherein the V85%...

Hi i am not goin goin going to lie Fluid Mechanics is not my strongest subject. Im struggling to calculate the Metacentric height. Ive got the following: Total weight of assembly (W) = 2.447kgf Ajustible weight (w) = 0.204kgf Breadth of pontoon (L) = 360mm Height of metacentre...

a beam with an effective span of 8.2m is required to carry uniformly disributed loading of gk = 12 kNm-1(in additon to its own self weight) and qk = 10kNm-1. design a suiable reinforced concrete beam using strength class C30 concrete and high yield reinforcement could someone check my...

believe i have to do the calculations too for the equations

a steel rod, 40mm in diameter and 1.00m long is pinned at each end calculate the euler bucking load Answer: using PE = pie sqaured 210x10cubed kN/mm x 1.25 x 10power 5mm to the 4 divided by 1000mm sqaured =259.1kN b) indentify three other possible end fixity conditions for the...

steel floor beams span 7.0m and are at 4.2m spacing. the beams are fully laterally restrained by precast concrete floor slabs, 180mm thick, which they support. the floor has to support a speciified imposed load of 5.0 kNm-2. determine a suitable grade S275 steel universal beam section...

thank you pongo this is what i worked out

sorry that n is meant to be pie

a steel rod, 40mm in diameter and 1.00m long, is pinned at each end i) calculate the euler buckling for the rod ii) identify three other possible end fixity conditions for the rod and demonstrate how euler buckling load would be affected in each case iii) explain the relation between the...
