  1. Most of the hand sanitiser gels have a high alcohol content - among other ingredients...

    There were a number of incidents where people were stealing the gel from dispensers for "home use" - either distilling the ethanol off or simply drinking it.

    I suppose it's the equivalent of the old Meths drinkers. Never mind the taste, feel the alcohol!

  2. The term is "loading gauge" for a particular line. It includes not only the height and width of bridges and tunnels, but also the curve radii (especially if combined with a tunnel) to make sure that the train can clear any obstruction - including the platforms (remember the tube & "mind the gap!").

    It should also include the weight limitation of the track and its bed - mainline routes are much more expensive to maintain and build than "light railway" tracks).

    I suspect that the US goods trains are so large that it's easy to miss a small detail.

  3. From the numberplate of the other car, I'd guess this is not in the UK (nor probably the EU!).

     

    I'd hate to be a passenger in the front seat in a minor shunt - there is no seatbelt...

    I suspect that the structural integrity is severely compromised - rather like the old UK convertible saloons that were created by removing the roof - and not adding structural reinforcements (e.g. Hilmann Minx IIRC!)

  4. Helmsman put the helm over to turn to starboard (the right looking at the front of the ship)...

    However, a ship (or any boat with a rudder) - will always "run wide" - in this case, the bow turns to starboard, and the stern swings to port. Basically, the ship will pivot about the centre.

    Put it down to helmsman training - possibly (from RYA instructors' facebook) the bridge is quite far forward, so it isn't as obvious as normal what's happening behond!

  5. Restricted visibility sound signals:-

     

    One long blast every 2 minutes when underway ...

    Quote

    Fog, mist, falling snow, heavy rainstorms, sandstorms or any other similar causes can make conditions that hamper visibility. Sound signals for vessels in restricted visibility, whether underway, at anchor or aground, day or night, are the subject of Rule 35 (COLREGS). The bell and gong are added into the mix of whistle sounds used as options for restricted visibility signals. Rule 35 is fairly complex, and it is advised to have a highlighter in hand while reading through it.

    The Rules of the Road state when underway ‘vessels shall sound at intervals of not more than two minutes’ the prescribed sound signal. Why a two minute rule? A requirement for all vessels is to maintain a proper look-out by sight and hearing. In restricted visibility, the two minutes allows the look-out to listen for sound signals from other vessels groping their way through the fog. COLREGS lists the following sound signals for vessels underway:

    A power-driven vessel making way shall sound one prolonged blast.

    A power-driven vessel underway but stopped shall sound two prolonged blasts.

    And you're waiting for someone else's sound signal...

     

    That from the "Regulations for the avoidance of collisions at sea" - normally call the "Collision Regs"!

     

    Glad you had a good time,  coming back with a good family time.

    ps - the fog horns from a lighthouse were louder - but they decided that they aren't needed nowadays

  6. IF you look at the bogey furthest away, it's actually created deep scores in the tarmac surface.  It's not on a set of rails.

    The front bogey is located on rails.

     

    Assume the tramcar was travelling left to right, something else was moving from back to front (as we see the picture). That would :-

    a) damage the front left of the tram (as photo)

    b) impart a torque on the tram to turn the front towards us and the rear away (clockwise from the top)

    Let's assume the driver hit the emergency brakes,  than the weight transfer would be rear to front, an impact would also raise the rear of the tram, allowing the wheels to jump the rails.

    Once the wheels are free of the rails, the bogey will rotate to the least resistance - i.e parallel to the direction of travel. It also looks like the bogeys have been displaced from their normal positions (the trams leaning)...

  7. When I had my Morris Minor, I contacted Dunlop regarding the age of the tyres.

    Back in last century, they only used a 2 digit code, so they could tell me that they were 10, 20 or 30 years' old, but not which...

     

    They looked OK, but the tread had hardened to the point that I could do Doughnuts quite easily on damp roads. They didn't lask.  The Nankings I tried weren't much better, but the Kuhmos were OK...

    And yes, I was using radials, not the crossply (the Insurers didn't seem upset!).

  8. It's not in a condition to meet the MOT requirements (you have to maintain the car - i.e. if the lights are wrenched off, then they need to be replaced).  However:-

     

    1) The sign is "Village Gasoline" on the pump - this suggests it in the US - and I've no idea what regulations apply there....

    2) It may be legal in the UK - if you have booked an MOT test and are driving the most direct route to the testing station (but no deviations), then you can drive a car without an MOT.

    Driving to a repair shop is a bit dodgier - you may have invalidated your insurance by not haveing the car in "a roadworthy condition"...
