That's the whole point of using a tripod, it allows you to shoot at slow shutter speeds without introducing camera shake.your shutter speed is at 1/40 and that is way too slow for the focal length you're shooting at to get any sharp images.
That only applies if you are hand holding. If you are using a tripod you can use any shutter speed that stops subject motion, if the subject is static then you can have very long exposures with no loss of quality.What you can do is increase you ISO to get a faster shutter speed of double your focal length. For this you can use your tripod or hand hold it, both will work.
