As Mangala is malefic (Paapa Graha) by its nature, thus Tuesday generally is considered to be a day for Paapa Karmas (sinful, unethical, cruel actions) only if certain benefic work isn't specified for it. Its nature is cruel (in ancient Sanskrit - "Ugra" or "Karura"), thus all "cruel" works are good on Tuesday. In combination with "cruel" Nakshatras (Magha, Bharani, Poorva Phalguni, Poorvaashadha and Poorvabhadra Pada) activity related to this Nakshatras will be very fruitful. As for effectiveness - Tuesday is effective during night-time. This day is auspicious for everything related to red color, "warlike" works, working with overcoming problems and surgery (as Mangala, a ruler of this day, rules conflicts, problems, wars, etc.). All works that somehow are related to overcoming difficulties are very auspicious at this day (as Ganesha, who's responsible for wisdom and energy that's needed in problem solving, is a tutelary Devata of Tuesday. It's very auspicious to appeal to Ganesha while trying to do something important during Tuesday). Adhi-Devata of Tuesday is Bhumidevi, who's called Mother of Earth and is responsible for Prithvi Mahabhutani. Thus, Tuesday is a very special day for any actions or work related to Bhumi and Prithvi.
